Abstract: Disclosed herein are an exemplary apparatus, system, and methods (e.g., Tactical Passive RFID transponder gloves with Morphological Actuation) comprising a glove made predominately of a resistive fabric that varies resistance per degree of deformation; comprising near field communication RFID tag readers, and a controller coupled to the glove to evaluate the varied resistance. A method of classifying RFID tags is also disclosed.

Abstract: A jump starting apparatus configured for jump starting a vehicle battery includes a rechargeable battery, a first battery cable having a first battery terminal connector for connecting the jump starting apparatus to a first battery terminal of the vehicle battery, a second battery cable having a second battery terminal connector for connecting the jump starting apparatus to a second battery terminal of the vehicle battery, a first conductor bar or plate connecting a conductor of the first battery cable to a first tab or terminal of the rechargeable battery, and a safety control system or circuit configured for detecting when the jump starting apparatus is properly connected to the vehicle battery and then switching on power from the rechargeable battery to the vehicle battery only when the jump starting apparatus is properly connected to the vehicle battery.

Abstract: A rechargeable battery assembly includes a rechargeable battery having a positive terminal and a negative terminal, and a rigid electrically conductive frame electrically connected to at least one of the positive terminal or the negative terminal of the rechargeable battery. The rigid electrically conductive frame is bent along multiple axes and includes a plurality of conductive frame members that are mechanically coupled together. The rigid electrically conductive frame surrounds the rechargeable battery on at least five sides, thereby providing structural stability to the rechargeable battery assembly during storage and use.

Abstract: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Abstract: An apparatus for jump starting a vehicle includes a handheld booster device comprising a rechargeable battery pack, a control circuit, a power switch, and an output port, wherein the control circuit detects when it is safe to couple the handheld booster device to the vehicle's battery and connects the rechargeable battery pack to the output port thru the power switch; and a jumper cable device comprising a plug and a pair of cables integrated with the plug, the plug being configured to connect to the output port of the handheld booster device in a specific orientation.

Abstract: A hand held, portable jump starter device includes a housing having a multi-cell rechargeable battery, a USB input port for receiving a charging current to recharge the multi-cell rechargeable battery, and an output port for providing jump starting current to an external vehicle; a USB charge circuit including a DC-to-DC converter circuit for upconverting an input voltage on the USB input port to a higher charging voltage for recharging the multi-cell rechargeable battery; a pair of series connected transistor devices for controlling current flow into and out of the multi-cell rechargeable battery; a control circuit for detecting the voltage of the multi-cell rechargeable battery and configured to turn off the USB charge circuit to prevent over charging of the multi-cell rechargeable battery if the detected voltage exceeds a threshold value; and a battery charge controller configured to prevent over discharging of the multi-cell rechargeable battery.

Abstract: Aspects of the disclosure relate to phenylalanine ammonia lyase (PAL) enzymes, including engineered PAL enzymes, and their use in catalyzing chemical reactions.

Abstract: A rechargeable battery jump starting device and a rechargeable battery assembly for use in the portable rechargeable battery jump starting device. The portable rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery assembly to a battery being jump started.

Abstract: A hand held, portable jump starter device includes a rechargeable battery with a plurality of battery cells connected in series, and a battery cell equalization circuit connected to the rechargeable battery. The battery cell equalization circuit includes an individual battery cell equalization circuit for each of the plurality of battery cells, with each of the individual battery cell equalization circuits configured to discharge a particular battery cell upon the particular battery cell reaching a cell voltage exceeding a pre-determined upper voltage threshold until the particular battery cell reaches a pre-determined lower voltage level below the upper voltage threshold, and where the individual battery cell equalization circuits are configured to charge lower voltage individual battery cells at a higher rate allowing lower voltage individual battery cells to catch up in voltage to an individual battery cell having a highest voltage.

Abstract: A jump starting apparatus for boosting or charging a depleted or discharged battery having a positive polarity battery terminal and a negative polarity battery terminal includes a rechargeable battery, an output port, a battery cable assembly, and a safety control system or circuit.

Abstract: A battery assembly device for a battery jump starting device. The battery assembly is configured to maximize electrical conductivity from a battery pack of the battery jump starting device to a battery to be recharged.

Abstract: A vehicle battery jump starter with air pump device includes a vehicle battery jump starter and an air pump disposed within a cover. An internal battery is also disposed within the cover and connected to the vehicle battery jump starter and the air pump. A port is provided so as to provide connection to the device from an external vehicle battery. The air pump is configured such that it is powered by the external battery in a first mode of operation.
