Abstract: A tilt switch includes a central electric contact member and a first electric contact terminal adapted to be mounted on a support. The central electric contact member defines a rolling area. An electrically conductive ball member is rollable on the rolling area. An electrically conductive shell member is mounted on the support to confine an accommodating space for the ball member, and has a second electric contact terminal in electric contact with the first electric contact terminal. Once the rolling area is tilted, the ball member will move by virtue of gravity to contact with an inner peripheral surface of the shell member so as to establish an electrical connection between the central electric contact member with the first electric contact terminal.

Abstract: A method of fabricating a substrate having a conductive layer on opposing sides, with the conductive layers interconnected by a conductive via. The inventive method uses a dielectric substrate having a conductive layer deposited or laminated onto one or both of the substrate's opposing surfaces. For the situation of a metal layer on one side of the substrate, a laser drill is used to drill blind vias through the dielectric, stopping at the substrate/conductive layer interface. An electrolytic plating process is used to fill the via by establishing an electrical connection to the conductive layer. A second conductive layer may be deposited or laminated to the other surface of the substrate. If the starting structure has a conductive layer on both sides of the substrate, the drill is controlled to bore through the upper conductive layer at a comparatively high power and then continue at a lower power through the substrate.

Abstract: Automatic Speech Recognition (ASR) is achieved in wireless communications systems in which reliable ASR feature vector sequences are derived at a base station directly from digitally transmitted speech coder parameters, with no additional processing or signal modification required at the originating handset. No secondary channel need be provided for the transmission of ASR feature vectors. In operating on received speech coder parameters prior to conversion to a voice signal the present system and methods avoid the lossy conversion process and associated voice distortion. Since the received voice parameters are error protected during transmission they are received with greater accuracy. All, or a subset, of speech coding parameters, including, in appropriate cases, spectral envelope parameters, reflection coefficients, LSPs, LSFs, LPCs, LPCCs, and weighted LPCCs may be processed at a receiving base station or forwarded to another location for processing.
