Abstract: An actuating and sensing module is disclosed and includes a bottom plate, a gas pressure sensor, a thin gas transportation device and a cover plate. The bottom plate includes a pressure relief orifice, a discharging orifice and a communication orifice. The gas pressure sensor is disposed on the bottom plate and seals the communication orifice. The thin gas transportation device is disposed on the bottom plate and seals the pressure relief orifice and the discharging orifice. The cover plate is disposed on the bottom plate and covers the gas pressure sensor and the thin gas-transportation device. The cover plate includes an intake orifice. The thin gas transportation device is driven to inhale gas through the intake orifice, the gas is then discharged through the discharging orifice by the thin gas transportation device, and a pressure change of the gas is sensed by the gas pressure sensor.

Abstract: An x-ray focusing device generally includes a slide pivotable about a pivot point defined at a forward end thereof, a rail unit fixed with respect to the pivotable slide, a forward crystal for focusing x-rays disposed at the forward end of the pivotable slide and a rearward crystal for focusing x-rays movably coupled to the pivotable slide and the fixed rail unit at a distance rearward from the forward crystal. The forward and rearward crystals define reciprocal angles of incidence with respect to the pivot point, wherein pivoting of the slide about the pivot point changes the incidence angles of the forward and rearward crystals while simultaneously changing the distance between the forward and rearward crystals.

Abstract: A method for receiving a telephone call being transmitted on a network using Internet protocol (IP network) is disclosed. A request to handle the telephone call is received from an originating node on the IP network by a leader node on the IP network. A receiving node, having a receiving address, is selected to receive the telephone call. The receiving node is selected from a set of nodes comprising the leader node and at least one follower node, where each node in the set of nodes can receive the telephone call. The receiving address is transmitted by the leader node to the originating node using the IP network. The leader node causes the originating node to transmit the telephone call to the receiving node using the IP network.

Abstract: A toilet seat construction includes a seat member with an upper major surface for holding a stack of pliable seat sheets thereon. A retaining member has a rear portion mounted pivotally and turnable relative to the seat member so as to be superimposed upon the seat member. The retaining member has an opening bordered by two lateral retaining portions. When the retaining member is superimposed upon the seat member, the lateral retaining portions are superimposed upon lateral holding areas of the upper major surface of the seat member, and thus a body contact area of the stack of the pliable seat sheets is urged to protrude out of the opening for contacting the body of the user.
