Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

Abstract: Modular storage systems include load sensors disposed beneath or in association with platforms. The load sensors are pulse-sampled for signals corresponding to loads at time intervals, rather than continuously, in order to conserve electrical power. An item associated with a transaction is identified based on a change in the loads, as determined from the pulse-sampled signals. The platforms are aligned at horizontal or non-horizontal angles, and photovoltaic power sources with banks of photovoltaic cells are mounted to front edges of the platforms. When a user reaches over one of the photovoltaic cells to access an item on a platform, a level of power or voltage generated by the photovoltaic cell is diminished. The item closest to the photovoltaic cell having the diminished power or voltage, or a customer that accessed the item, may be identified accordingly.

Abstract: The present disclosure relates to reducing a potential difference among a slider body and a hard disc drive platter by providing a hard disc drive platter and/or slider body with a coating that includes one or more additives that can dissipate electrical charge.

Abstract: An apparatus is disclosed which provides distraction of the talo-tibial joint so as to allow performance of arthroscopic surgery of the ankle. The apparatus is readily connectable to a standard operating table and allows for adjustment of the amount of tension induced to the patient's ankle. The apparatus includes a unique foot engaging device which includes only two straps; a first calcaneus strap and a second dorsum strap. The straps are connected to one another and to the foot and ankle of the patient by use of hook and loop-type material fasteners. The use of such fastening material allows ready adjustment of the straps about the patient's foot and ankle so as to provide proper plantar and dorsiflexion when the cable of the distraction apparatus is attached to the ends of the calcaneus strap.
