摘要： Methods and apparatus for determining the speed of a signal species, such as an acoustic signal, in a multilayered medium is described. The multilayer medium, generally, has a first and second layer (e.g. oil and water), whereby first and second signals are transmitted across particular distances in the medium such that a second distance differs from a first distance, and whereby the time of flight of each signal can be used in order to determine the speed of the signals species in one or both of the first and second layer. In other words, in some cases, the speed of sound can be determined in oil and/or water, or the like.

摘要： An inertial sensor (16) includes a differential thermocouple (13) including first (4A) and second (4B) metal traces, a poly trace (6) with a first end connected to a first end of the first metal trace to form a first (−) thermocouple junction and a second end connected to a first end of the second metal trace to form a second (+) thermocouple junction. A gas mass (10) located symmetrically with respect to the thermocouple junctions is heated by a heater (8). Acceleration or tilting of the sensor shifts the relative location of the gas mass relative to the thermocouple junctions, causing differential heating thereof and generation of a corresponding thermocouple output signal.

摘要： An accelerometer module for use with a touch sensor on a device, a method of detecting acceleration using a touch sensor, and a computer program product for receiving the touch sensor data and producing output representative of acceleration. The accelerometer module provides a device with a touch sensor, such as a mobile phone, with the ability to sense acceleration, orientation, or both. The accelerometer module may sense acceleration along a single axis or multiple axis. Sensing acceleration along three axis may be useful for producing a handheld game controller or for providing input to many other applications. The accelerometer module applies a force against a deformable member to change the contact area between the deformable member and the touch sensor, wherein the contact area is a function of the amount of applied acceleration.

摘要： A liquid flowed detection system is disclosed for monitoring continuous and discontinuous liquid flow in a fluid circuit. The system includes a holding device for maintaining a drip chamber so that its elongated axis generally lies in a vertical plane. A light emitter is oriented to transmit light along an optical path through the drip chamber and intersecting its elongated axis. A light detector located in the optical path opposite the light emitter, generates a signal representative of light received from the light emitter. A processor receives information from the detector and generates a control signal representative of a variability over time of the light detector signal. When the control signal drops below a predetermined level, a flow absence signal is generated which is then correlated to the system's pump velocity corresponding to a time interval (T). If the flow absence signal occurs continuously in a comparison time interval (T), a warning signal is generated.
