Title: Microphone biasing circuitry and method thereof
Inventor: ANDREW JAMES HOWLETT
IPC: H04R19/04
Filed: 2013-04-11
Abstract: The host device has a device connector for forming a mating connection with a respective peripheral connector. A source of bias 102 is arranged to supply an electrical bias to a device microphone contact 117 of the device connector via a biasing path. A capacitor 225 is connected between a reference voltage (ground) node and a capacitor node 304 of the biasing path. A first switch 301 is located between the capacitor node 304 and the device microphone contact 117. Detection circuitry (602, fig 6a) detects disconnection of the peripheral connector and device connector; and control circuitry (601, fig 6a) controls the switch to disable the biasing path within 100µs. This removal of the bias voltage from the connector is said to reduce the occurrence of undesirable clicks or pops. Several embodiments of the invention are discussed.

Title: Pressure reducer assembly
Inventor: WILLI HECKING
IPC: F24H1/18
Filed: 2017-06-27
Abstract: The venting fitting is for drinking water heaters with an air cushion for receiving expansion water. The fitting comprises a housing 12 with a water inlet 14 and outlet 32, whereby in use water flows from the inlet through the housing to the outlet for tapping. An air inlet 72 is connected to the atmosphere and is separated from the water. A connection channel 68 connects the air inlet to an air outlet 74 and includes two backflow preventers 76,78 arranged in series. An air-filled pressure chamber is formed at least partially between the backflow preventers and exerts a pressure in an opening direction on the air-outlet-side backflow preventer 78 and in a closing direction on the other preventer 76. A moveable lifting element such as a piston 64 actuated by an annular diaphragm 44 limits the pressure chamber and is exposed to inlet pressure in the water inlet at one side and to the outlet pressure in the water outlet on the other side. The element moves when a pressure difference exists between the water inlet and water outlet, the movement causing a volume and pressure change in the pressure chamber to open or close the backflow preventers.
