Abstract: A hybrid player and a method of using the hybrid player to play a first stream and a second stream simultaneously while muting the second stream. The first stream continues to play until it is desired to replace the first stream with the second stream. Simultaneously, the first stream is muted and the second stream is unmated while simultaneously increasing a volume of the second stream.

Abstract: Apparatus and method are presented for supplying electrostatic discharges to a device under test. A discharge probe is employed for applying the discharges to the device. The probe is moved to preselected position points relative to the device during the test. The probe is displaced from one preselected position point to the next in response to position control signals supplied by a controller. The controller includes a memory for storing address data respecting the preselected position points.

Abstract: A thermostatic mixing valve and method of use thereof. The thermostatic mixing valve is controlled by the incoming hot and cold fluids, which are mixed in a mixing chamber, by a thermally responsive element disposed in the flow of the fluid mixture in a fluid outlet from the mixing chamber. A distributor for distributing the flow is controlled by the thermally responsive element. A drive is activated by pressure of the fluid and is connected to the distributor for controlling the position of the drive. The distributor is used to control the hot and cold fluid flows. Channels are provided to connect the distributor with one of the fluid inlets, to connect the distributor with the outside of the valve body to conduct away used operating fluid and to connect the distributor with the drive.
