Abstract: A life safety device includes a battery assembly with a rechargeable battery. Extended shelf life is achieved by annually initiating an over-discharge protection mode in which a battery protection circuit prevents current flow from the battery. The life safety device remains in the over-discharge protection mode until the device is connected to a charging power source at the time of installation. The battery assembly then exits the protection mode and enters its normal mode of operation.

Abstract: Systems and methods for registering a domain, including Internationalized Domain Names (IDNs), including receiving a request to register an IDN and determining a language category of the request. Code points of the request are converted to yield a generalized variant of the IDN. The generalized variant is compared to a stored database of registered IDNs that may include similar generalized variants of the registered IDNs. Based on the comparison, it is determined whether or not to resister the IDN. In the case the that IDN registration is allowed, the generalized variant of the IDN may be stored in the database to protect against later registration by similar IDNs. Converting the code points of the request may include identifying corresponding code points of variants within the language category, and converting each of the code points of the requested IDN based on a deterministic algorithm applied to the corresponding code points.

Abstract: A wireless device that can process signals according to multiple wireless protocols simultaneously and without signal loss. The wireless device may comprise an antenna and first and second wireless protocol circuitry. The first wireless protocol circuitry comprises a shared gain element that amplifies signals that are processed by each of the first and second wireless protocol circuitry. Since the third signals are amplified by the shared gain element prior to being split out to the respective protocol circuitry, the first and second portions of the amplified third signals do not have significant signal loss relative to the third signals provided by the antenna. Thus the wireless device can receive and process wireless signals according to both the first and second protocols simultaneously without any significant signal losses due to splitting of the receive signal.
