Abstract: A contact-based inductive sensing technique for contextual interactions on interactive fabrics is described. The technique recognizes conductive objects (mainly metallic) that are commonly found in households and workplaces, such as keys, coins, and electronic devices. An apparatus includes an array of a plurality of six by six spiral-shaped coils including conductive thread, sewn onto a four-layer fabric structure. The coil shape parameters were determined based on maximizing the sensitivity based on a new inductance approximation formula. Through a ten-participant study, the performance of sensing technique across 27 common objects was evaluated. A 93.9% real-time accuracy for object recognition resulted.

Abstract: A vehicle seat reinforcement device includes a leg portion mounted on a floor panel, a seat cushion frame slidably mounted on the leg portion, and a load reinforcing structure connected between the leg portion and the seat cushion frame, wherein when a seat belt anchorage load is transferred to the seat cushion frame, the seat cushion frame is locked to the leg portion by the load reinforcing structure.

Abstract: A DC voltage supply apparatus including a voltage detection unit, an enable signal processing unit, a latch unit, a control unit and a voltage transforming unit is provided. The voltage detection unit receives and detects a DC input voltage to generate an input voltage state signal. The enable signal processing unit receives the input voltage state signal and an enable signal, and determines a state of the enable signal according to the input voltage state signal. When the enable signal is ineffective, the latch unit latches the enable signal to keep an ineffective state. The control unit receives the enable signal, and generates a control signal. When the control signal is effective, the voltage transforming unit receives the DC input voltage and transforms the DC input voltage into a DC output voltage. When the control signal is ineffective, the voltage transforming unit stops receiving the DC input voltage.

Abstract: A server system including a rack, motherboards and direct current (DC) transformation units is provided. Each of the motherboards is inserted on the rack, and generates a power on signal. Each of the DC transformation units is on the rack and receives a DC voltage. When each of the motherboards is electrically connect to the corresponding DC transformation unit, each of the DC transformation units generates a standby voltage and a standby voltage ready signal to the motherboard according to the DC voltage so that the motherboard enters a standby state according to the standby voltage ready signal. When the motherboard corresponding to each of the DC transformation unit generates the power on signal, the DC transformation unit receives the power on signal and generates an operating voltage and an operating voltage ready signal to the motherboard, and the motherboard is turned on according to the operating voltage ready signal.
