  • Publication number: 20140326072
    Abstract: Embodiments of the present disclosure relate to methods, devices, and systems for determining occupancy of a user. One method to determine occupancy of a user includes sensing a change in resistance of a sensor element of an occupancy sensor, correlating the change in resistance to a force transmitted to the occupancy sensor, and determining an occupancy status of a user based on the force transmitted.

  • Patent number: 7701332
    Abstract: Embodiments of the present invention relate to methods, devices, and systems to monitor activity. One system to monitor activity includes a remote device including a home/away sensor and a transmitter. The embodiment also includes a local interface that receives a wireless signal from the transmitter and a base station operably coupled to the local interface. The base station can include a receiver for receiving signals from a number of sensors and a logic component that institutes rules to determine whether to initiate an alert based on one or more activations of the home/away sensor.

  • Patent number: 7608815
    Abstract: A method of compensating a photo sensor (and a corresponding photo sensor with compensation) insures the accuracy of the photo sensor, e.g., over environmental variations or photo cell variations. The method comprises: providing a first signal indicative of a light level; providing a second signal indicative of an environmental parameter, e.g., temperature; and calculating, responsive to the first signal and the second signal, a compensated signal that is indicative of an absolute light level. The calculating can be performed by a processor and utilize calibration and compensation information or parameters, which can be obtained experimentally.

  • Patent number: 6071184
    Abstract: A fluid deflection device for use in a work piece holder during a semiconductor wafer grinding process is disclosed. The fluid deflection device includes an annular, upstanding splash fence, and an attachment portion associated with the splash fence and configured to attach to the work piece holder, thereby to hold the splash fence in a position to inhibit fluid from flowing between rotatable and non-rotatable parts of the work piece holder.

  • Patent number: 6000998
    Abstract: A wafer edge grinding machine including a chuck rotatable about a first axis, a chuck basin having bottom and side walls surrounding the chuck and a fine aligner disposed over an open top of the basin and configured to deliver wafers to the chuck. The machine further includes a probe having a sensor contact surface and a shifting mechanism adapted to selectively withdraw the sensor contact surface to a storage position and extend the contact surface to a measurement position. The probe also includes a mounting structure adapted to secure the probe to one of the walls in the basin with the probe being mounted in the basis to position the contact surface adjacent the perimeter of a wafer disposed on the chuck. The shifting mechanism includes a remotely operable control adapted to allow a user to operate the shifting mechanism from a location remote from the basin.

  • Patent number: 4909164
    Abstract: A hazardou waste incinerator which utilizes a cyclotron resonance plasma. The plasma is generated by introducing vaporized hazardous material and a feed gas into a vacuum chamber. The chamber has a magnetic field source and an electromagnetic radiation source. The cyclotron resonance plasma is produced by the resonance that occurs when the frequency of the electromagnetic radiation is set equal to that of the gyration of electrons or other charged particles in the magnetic field according to the formula: F.sub.res =(1/2.pi.)(qB/m) hertz Where q is the charge of the electron or ion, B is the strength of the magnetic field and m is the mass of the electron or ion. The strength of the electromagnetic radiation is adjusted so that the flowing gases are ionized, forming a plasma. During the reaction, the charged particles collide with neutral particles, providing both ionization and fragmentation (the breaking up of high-mass molecules into lower mass fragments).
