The nickel–cadmium battery (Ni-Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.A Ni-Cd battery has a terminal voltage during discharge of around 1.2 volts which decreases little until nearly the end of discharge.ġ. High quality and high reliability. Nickel cadmium battery is manufactured under very strict quality management and has excellent quality dependence. There are four types commonly used: standard type, consumer type, high-temperature type and high current discharge type, which can be applied to any wireless device.Ĩ. ![]() A wide range of applications. The capacity of nickel cadmium battery ranges from 100mah to 7000mah. Due to the special material used in the sealing ring and the effect of sealant, the leakage phenomenon of Ni Cd battery is rare.ħ. Nickel cadmium battery can be used freely in the process of charge-discharge or storage. Reliable safety valve. The safety valve provides maintenance-free function. High-temperature batteries can be used at temperatures of 70 degrees Celsius or higher.Ħ. Wide range temperature adaptability. Ordinary nickel-cadmium batteries can be used in high or low-temperature environment. High rate charging performance. The nickel-cadmium battery can be quickly charged according to the application needs, and the full charge time is only 1.2 hours.ĥ. The Ni-Cd battery has a long storage life and few restrictions, so it can be charged normally after long-term storage.Ĥ. Excellent discharge performance. In the case of high current discharge, nickel-cadmium battery has low internal resistance and high voltage discharge characteristics, so it is widely used.ģ. High life. The Ni Cd battery can provide more than 500 charge and discharge cycles, and its service life is almost equal to the service life of the equipment using the battery.Ģ. Other uses: electric shavers, massagers, electric toothbrushesġ. Communication equipment: cordless phones, walkie-talkieĥ. Electronic toys: remote control cars, remote-control boats, aircraft, model aircraftĤ. Power tools: electric drills, planers, saws, power grantedģ. Lighting: emergency lighting, emergency power supply, solar lights, searchlights, flashlightsĢ. Packaging: Standard export package or customized packageġ. Nonetheless, for applications where reliability and durability are more important than high energy density, a NiCd battery pack like this one can be an excellent choice. However, it's worth noting that NiCd batteries have a lower energy density compared to newer battery technologies like lithium-ion, so they may not last as long between charges. This means it can provide a steady supply of power for a range of devices, from portable radios to remote control toys. This particular NiCd battery pack has a voltage of 3.6 volts and a capacity of 1200mAh. It is known for its reliable performance and ability to withstand frequent charging and discharging cycles. A nickel-cadmium (NiCd) battery pack is a type of rechargeable battery that has been widely used for many years.

The checkbox in the screenshot refers to the Firefix Password Manager without Master Password, although it doesn't check and it works in both cases. (My initial research reveals complaints and vulnerabilities in old (pre-Sync) versions of Firefox, including confusion about which login components are encrypted and which are not, suggestions that new Sync is "zero-knowledge" (but no clarification on what is stored in plaintext locally), claims that LastPass uses JavaScript for encryption and is therefore inherently insecure and, most confusingly, endorsement of LastPass from Mozilla.) I assume the threat model is something like daily browser use, including entering passwords for online banking etc, and storing and sharing login credentials between browser installations on different machines you own.)

![]() Let's talk about a trap when using linear regulators. Įdit - just searched for 78_ based switching regulator circuits & found several using pretty much an identical and familiar-looking configuration, though my version was adapted for much higher current & variable voltage: The voltage adjustment is the slotted pot on the rear panel. The left hand front panel switch is the on/off one and the right is a spring loaded one that switches the meter to voltage rather than current, while pressed. The aluminium can across in front of the transformer is a mains RFI filter. The socket at the top of the back panel with white wires is a plug-in 12V output for equipment, the bottom corner socket is main input. Well, it still works, so it can't be all that bad! Most of the other small components are on the tagboard. The diode that goes with that is attached directly to the top of the larger cap and insulated with duct tape The blue capacitor is the output smoothing and the round aluminium item at the side of the two caps in the top view is a large "pot core", with the winding for the inductor. ![]() The bridge rec is the part with four upright terminals bolted to the base of the case in front of the big capacitor & the big silver cap the initial smoothing from that. I remember the principle but have no idea of the actual circuit, so I cannot provide that, sorry. The outline regulator was in the applications notes of a data book, for some make of 78xx or 317 voltage regulator, using one of those as voltage sense and a "high current" driver for external transistors with some positive feedback for hysteresis. The only transformer I could obtain at the time that had an adequate power rating was a 24V one, far too high to regulate conventionally to 12V or less without dissipating crazy amounts of heat - so it's a "secondary switcher" design, what would now be called a buck regulator. ![]() It also has 40 year accumulation of dust inside, which I cannot remove from the deeper recesses easily but it's a realistic DIY high current adjustable supply, if a slightly odd one. The construction is somewhat primitive and cringeworthy by my presents standards, but it is around 40 years old I remember building it when I still has a shed as a workshop at my parents house. Or this is something similar to what you want, as a DIY one I remembered seeing it in my garage a few weeks ago while looking for some other items. The number of wires and plugs used varies greatly by region since each country is evolving their electrical grids at a different rate and over time so these are only provided as a good starting point and general guide.If you want an off-the-shelf one, look at an EP-925, sold under various brand names Manson, Voltcraft etc. The opposite is also true - you can sometimes gain kW when you convert from 50 Hz to 60 Hz because you speed the engine RPM up. This is mainly because you have to slow the engine RPM down and make adjustments so the overall kW or kVA output will be lower. When considering a backup power generator, keep in mind that the frequency can often be changed by an accomplished power generation technician or electrical contractor but you do typically see a performance loss on most generator sets when you convert from 60 hertz to 50 hertz. Some applications use specialized higher voltages (such as 4160 V or 13,400 V) but these are on a more unique basis and typically involve transformers so those are not included. Single-phase power is primarily for residential use (such as homeowners and what you would find in a hotel) while 3-phase electric power provides more stable, heavy-duty power for most industrial applications like manufacturing plants, commercial facilities, data centers, telecom towers, hospitals, food processing, and utility power plants. There are approximately 40 countries that use 60 Hz while the rest typically run on 50 Hz current. Each country is listed with the volts and frequency (also referred as Hertz or Hz and is referring to cycles per second) commonly found in each geographic area. This chart includes information on voltages and frequencies found across the globe.

In 2018, when Patrick Byrne, then Overstock’s chief executive, wanted to sell the retail business to focus on cryptocurrency technology, Bed Bath & Beyond was a potential buyer, Mr. Johnson saw an opportunity for his own company. When the home-goods retailer filed for Chapter 11 bankruptcy in April, Mr. “We will probably have both logos for a little bit, but the goal is to transition as quickly as possible to Bed Bath & Beyond,” Mr. It’s betting Bed Bath & Beyond’s name can help change that. Johnson said, its name was holding it back in the eyes of consumers. The company has since moved away from selling only furniture at basement bargain prices, but ultimately, Mr. Johnson, who has been at the helm since 2019.įor years, has been trying to find a way to update its image as a liquidator, which is how it started in 1999. ![]() “I can’t tell you how many times I’ve been asked over the years when we’re going to change the name of Overstock,” said Mr. It might settle on Bed Bath & Beyond, he added, but other names are being considered, too. Company executives plan to eventually bring back Bed Bath & Beyond’s popular wedding registry.Īs Overstock folds the bankrupt retailers’ assets into its own operations, it is considering renaming its business entirely, said Jonathan Johnson, the company’s chief executive. Overstock’s mobile app and its rewards program will also be rebranded. Starting in August, about a month after the final Bed Bath & Beyond stores in the United States close, customers in the country who visit will be redirected to. The change will roll out in Canada in early July. Overstock, which last week paid $21.5 million to acquire the bankrupt retailer’s intellectual property, said on Wednesday that it would start operating its website under the Bed Bath & Beyond name. Soon, will become Bed Bath & Beyond - at least in digital form. Compared to pessimists, optimists are also less likely to develop high blood pressure (Everson, Kaplan, Goldberg, & Salonen, 2000), suffer from stress-induced changes in immunity (Kubzansky, Sparrow, Vokonas, & Kawachi, 2001), and even develop heart disease in the first place (Brydon, Walker, Wawrzyniak, Chart, & Steptoe, 2009). Optimistic people are also less likely to need rehospitalization after a coronary bypass or repeat cardiac operations (Scheier et al., 1999 Helgeson, 2003 Cauley et al., 2017). Rather than trying to avoid, ignore, or withdraw from a health concern, optimistic people are more inclined to seek practical support, cognitively restructure, or reinterpret the situation positively, among other coping methods (Solberg Nes & Segerstrom, 2006). Optimists may also take a more approach-focused method of dealing with health stressors. ![]() Specifically, Radcliffe and Klein’s (2002) research studied 146 middle-age adults and found that those with high optimism were more informed about heart attack risk factors, as well as the role of other risk factors on their health: stress, alcohol consumption, nutrition, smoking, fat consumption, and exercise. Optimistic individuals also tend to be more aware of their health status and how to stay that way. Similar findings of lower distress have been reported in individuals undergoing treatment for breast cancer (Carver et al., 1999). In a study of head and neck cancer patients, optimistic patients reported a higher quality of life both before and after treatment, suggesting that their positive outlook buffered the effects of health-related distress (Allison, Guichard, & Gilain, 2000). ![]() Several studies illustrate the different ways that optimism positively impacts our health. 52) explanatory style definition, “The basis of optimism does not lie in positive phrases or images of victory, but in the way you think about causes.”įrom here, we can see where the idea of ‘learnability’ originated.Ī few benefits of optimism include the following. 879) defined optimism from a dispositional standpoint, as “an individual difference variable that reflects the extent to which people hold generalized favorable expectancies for their future.”Īccording to Seligman’s (2007, p. Optimism is often considered the opposite but can be thought of in different ways.Ĭarver et al. Pessimism has been defined as: “ anticipation of good or bad things to happen in the future” (Carver, Scheier, & Segerstrom, 2010). How people can learn to become more optimistic – learned optimismīefore examining the findings on optimism’s benefits, let’s consider exactly what the two entail.Its impact on health, wellbeing, and success.The individual benefits of optimism, compared to pessimism.Some of his earlier work began to consider how optimism and pessimism were related to how people explained the cause of challenges and adverse events, which set the stage for more studies into other subjects: His interest shifted, and he started to look into how we could condition individuals to be more optimistic instead (Peterson, 2000). ![]() Learned optimism is very much a positive psychology concept it’s the opposite of learned helplessness: a phenomenon whereby individuals believe they are incapable of changing their circumstances after repeatedly experiencing a stressful event (Abramson, Seligman, & Teasdale, 1978 Seligman & Garber, 1980 Maier & Seligman, 2016).Ĭoming originally from a clinical psychology background, and with a lot of his work centered on pessimism, Seligman became curious why some individuals don’t feel helpless even when conditioned to do so. The aim of positive psychology is to begin to catalyze a change in the focus of psychology from preoccupation only with repairing the worst things in life to also building positive qualities. It’s also the title of Seligman’s well-known book, which delves into the theory a little further. Put succinctly, learned optimism is a concept that says we can change our attitude and behaviors by recognizing and challenging our negative self-talk, among other things. ![]() Learned Optimism: Martin Seligman’s Book Summary.What Is Learned Optimism in Psychology?. |
