Abstract: A battery pack management system provides information such as remaining capacity and/or run time to empty for a battery. A time taken for a battery voltage to drop a threshold amount is measured and used to determine a remaining capacity of the battery. The time may be associated with a temperature and current of the battery. The remaining capacity of a battery is calculated by monitoring a discharge of the battery. For example, current drawn from the battery is monitored over a period of time and an initial amount by which the battery has been discharged is calculated. Compensation of this initial amount is carried out in order to take into account factors such as temperature, self-discharge rate and age of the battery.

Abstract: The present disclosure provides a system and method for relieving stress and providing improved heat management in a 3D chip stack of a multichip package. A stress relief apparatus is provided to allow the chip stack to adjust in response to pressure, thereby relieving stress applied to the chip stack. Additionally, improved heat management is provided such that the chip stack adjusts in response to thermal energy generated within the chip stack to remove heat from between chips of the stack, thereby allowing the chips to operate as desired without compromising the performance of the chip stack. The chip stack also includes an array of flexible conductors disposed between two chips, thereby providing an electrical connection between the two chips.

Abstract: Disclosed is a programmable pulse width discriminator circuit operable to receive a set of parameters from a user and indicate when an input signal satisfies conditions set by the user-defined parameters. The input signal is sampled by the pulse width discriminator circuit to detect a desired state of the input signal. The user may set the parameters such that the pulse width discriminator indicates the condition wherein the number of consecutive samples for which the input signal is the desired state is (i) greater than a first threshold value, (ii) less than a second threshold value, or (iii) between the first and second threshold values. In these embodiments, the user sets the first and second threshold values and selects which set of conditions are indicated by the output of the circuit.

Abstract: A protocol for collision avoidance in inter and intra basic service set broadcast/multicast communication in a wireless network is disclosed. An access point reserves a broadcast transmission time and conveys that reservation to each of its associated stations. Using a beacon or an action frame, the transmission reservation time is sent to all stations and other neighboring access points within range of the primary access point. Upon receiving the broadcast transmission time reservation, each station associated with the reserving access point and any neighboring access points set their network allocation vector thus preventing frame transmission or reception during the now reserved transmission time.

Abstract: A detector recovers servo data from a servo signal generated by a read-write head, and determines the head-connection polarity from the recovered servo data. Such a detector allows a servo circuit to compensate for a reversed-connected read-write head, and thus allows a manufacturer to forego time-consuming and costly testing to determine whether the head is correctly connected to the servo circuit.
