InactiveUS7061381B2Improve rangeReasonable distanceSonic/ultrasonic/infrasonic transmissionRecord carriers used with machinesRadio frequencyTransceiver
A transceiver preferably embedded within a wearable security watch, PDA, or other device which achieves a variety of wireless ultrasonic and / or radio-frequency based functions, including digital identification and proximity and sensation monitoring of assets, individuals, pets, and the like. The portable or wearable device realizes these functions by periodically polling and receiving information tags within the transmitting distance of the device. The invention can help reduce the likelihood of the theft, loss, or misplacement by detecting that a tag associated with or attached to an entity has left an individual's proximity and sounding an alarm. The device can also assist individuals with sensory impairments, including persons who are deaf, diabetic, and the like, by detecting a tagged entity as it enters the space around an individual, or by detecting environmental stimuli, such as excessive heat in an individual's proximity or vital sign changes, and sounding an alarm.

An optical proximity correction method is provided using a modified merit function based upon yield. Known failure mechanisms related to layout geometries are used to derive yield functions based upon distance values between layout features, such as, edge features. In comparing the edge points on the predicted layout pattern with the corresponding point on the design layout pattern, a yield test is first undertaken before movement of the points on the predicted layout pattern to a position of higher yield. Where yield is acceptable, no further movement is made. Where incremental movement of points results in coming within acceptable proximity before acceptable yield is reached, the point is flagged for further consideration.

Fluid Assisted Gas Gauge Proximity Sensor
InactiveUS20100103399A1Error is commonHigh bandwidthPhotomechanical treatmentPhotographic printingProximity sensorPressure transmission
A fluid assisted gas gauge coupled to a pressure sensor enables proximity measurements to be made with a high bandwidth. A two-chamber gas gauge, containing a gas-filled measurement chamber and a fluid-filled transfer chamber and a diaphragm separating the two chambers, exhausts gas onto the surface being measured, while the incompressible fluid transmits the pressure to a pressure sensor. By minimizing the gas volume of the gas gauge, the response time is enhanced. In addition, the incompressible fluid permits the pressure sensor to be remotely located from the point of measurement without sacrificing the response time performance. In an embodiment, a differential bridge version of the fluid assisted gas gauge reduces common mode effects.
