Title: Highly sensitive piezoresistive element
Inventor: WILNER LESLIE BRUCE
IPC: H01C17/00
Filed: 2007-10-05
Abstract: A mechanical-to-electrical sensing structure has first and second movable blocks formed in a handle layer. A first hinge is coupled to the first and second movable blocks and configured to resist loads other than flexing of the first hinge. The first hinge is formed in the handle layer. A first gauge is separated from the first hinge and aligned to provide that a moment tending to rotate one of the first or second blocks relative to the other about the first hinge applies a tensile or compressive force along a length of the first gauge. The first gauge is formed from a device layer with an oxide between the device and handle layers. The sensing structure is made from an SOI wafer, and the first gauge is protected during an etching away of handle material beneath the first gauge by an oxide between the device and handle layers and an etch-resistant oxide or nitride on exterior surfaces of the first gauge.

Abstract: The teachings herein present a method and apparatus for protecting usage restriction data that governs usage of an electronic device. A cryptographic circuit supports secure and non-secure accesses. When non-securely accessed, it is operable only to verify the stored usage restriction data, and, when securely accessed, it is operable to generate a new message authentication code for changed usage restriction data, for subsequent authentication of that data. The usage restriction data may be stored in non-secure memory and may include static and dynamic parts. One or more embodiments include a secure circuit indicating whether the device has been initialized. The cryptographic circuit outputs a message authentication code for the static part using a permanent device key from the secure circuit, only if the device has not been initialized, and outputs a message authentication code for the dynamic part as needed to support authorized changes to the dynamic part.

Title: Sound signal processor and delay time setting method
Inventor: MATSUI TAKESHI
IPC: H04M1/60
Filed: 2008-06-05
Abstract: Even if an echo chancellor using an adaptive filter is under a condition that the system transmission delay is not constant, an appropriate delay time is set in a delay circuit capable of absorbing the system delay so as to produce a marked echo cancelling effect at all times. The time difference of the transmission path until the reproduction sound signal inputted to a delay circuit is inputted through the space from the speaker to the microphone as a processing subject signal of an adaptive filter system is obtained, and the delay time corresponding to the time difference is set in the delay circuit. When the distance between the speakerand the microphone is set short and the delay time of the delay circuit is set zero, the obtained time difference indicates the system transmission delay of the transmission path. Namely, a delay time corresponding to the system transmission delay can be accurately set in the delay circuit.
