The flexible polymer casing is infused with a conductive material at at least one location to form at least one infused electrode that extends from an exterior of the flexible polymer casing to an interior of the flexible polymer casing, and the at least one infused electrode is coupled to the circuitry so as to allow the signal to pass from outside the flexible polymer casing to the circuitry. A polymer in a portion of the flexible polymer casing that is infused with the conductive material at the at least one location is cross-linked with a polymer in a portion of the flexible polymer casing that is not infused with the conductive material.

Abstract: Disclosed are systems and methods for using one or more light sources and associated photodetectors to determine different physiological parameters of a subject based on the subject's activity state. A processor may, for example, be configured to determine, based at least in part on data received from an accelerometer at a first time, that a first physiological parameter of the subject is to be determined, to cause the light source(s) to operate in a first manner and process signals from the photodetector(s) to determine the first physiological parameter, to determine, based at least in part on data received from the accelerometer at a second time, that a second physiological parameter of the subject is to be determined, and to cause the light source(s) to operate in a second manner and process signals from the photodetector(s) to determine the second physiological parameter.

Abstract: Disclosed is apparatus including a power source, an ECG front end, a processor, and a computer-readable medium. The ECG front end is configured to receive a signal corresponding to a cardiac waveform, and the computer-readable medium is encoded with instructions which, when executed by the processor, cause the apparatus to (a) determine a first temporal window during which a first instance of a first portion of a cardiac cycle is expected to appear in the cardiac waveform (b) at a start of the first temporal window, apply a first amount of power from the power source to the ECG front end, and (c) at an end of the first temporal window, at least partially reduce an amount of power applied from the power source to the ECG front end.

Abstract: Apparatuses and methods are disclosed for monitoring and evaluating exercise-related activities performed by a subject. A health monitor comprising an accelerometer, at least one physiological sensor, and digital processor is configured to be supported by a subject and identify an activity type (e.g., running, biking, swimming) from among a plurality of different activities. The health monitor is further configured to determine from motion data and/or cardiac data levels of health benefits received from the exercise. The health benefits may be based on standards established by recognizable health entities, so that the reported health benefits are less susceptible to errors associated with conventional step counting.

Abstract: Counterfeit coin sensing apparatus including a transport system for continuously directing a plurality of successive coins along a feed path. A first coin sensor is disposed along the feed path for producing a denomination output signal corresponding to the diameter of each coin, and a second coin sensor is arranged along the path to produce a phase and amplitude displacement output signal corresponding to the metal content of the coin. The output signals from the two sensors are received by an acquisition system which converts the signals into corresponding standardized signals and then directs the standardized signals to an analysis system which compares the denomination and phase and amplitude displacement signals with stored signals representative of valid coins.

The fiber optic assembly includes an optical fiber having a first end and a second end, the optical fiber being subject to bending upon application of a transverse load to said housing. Means for mounting the optical fiber in the housing so as to permit bending of the fiber in response to application of a transverse load to said housing are provided, the degree of bending being sufficient to cause a significant decrease in passage of light through said fiber when said fiber is bent. Means permitting introduction of light into said optical fiber at the first end of the optical fiber and means for permitting the exit of light from the second end are also provided.

Abstract: An automatic vehicle detection system within a toll collecting system has a scanning laser unit positioned on one side of a roadway, a vertical photoelectric detector on the opposite side of the roadway and a treadle extending across the roadway. The laser beam scans the height of the detector at regular intervals, and the detector produces a first signal indicative of a vertical dimension of an object (car or truck) intercepting the laser beam. The treadle detects each set of wheels and produces a second signal indicative of a horizontal length of the object. A control circuit uses the first and second signals to generate a count of the number of objects and to categorize each object as one of a plurality of known vehicles.
