  • Patent number: 11513635
    Abstract: A processing system for an input device comprises sensor circuitry. The sensor circuitry is configured to operate sensor electrodes for input sensing during a first sensing frame. During a first period of the first sensing frame the sensor circuitry is configured to drive a first portion of the sensor electrodes with a sensing signal, drive a second portion of the sensor electrodes with a guarding signal, and drive a third portion of the sensor electrodes with a reference signal. The guarding signal and the sensing signal have at least one characteristic in common selected from the group consisting of amplitude, phase and frequency. The third portion of the sensor electrodes overlaps a first gate line of a display panel selected for updating during the first period.

  • Patent number: 11137856
    Abstract: A sensing device comprises sensor electrodes arranged in an array of rows and columns, and vias. A first vias is arranged in a first direction, and corresponds to a first column of sensor electrodes adjacent to a first side edge of the sensing device. A second via is arranged in a second direction different than the first direction, and corresponds to a second column of the sensor electrodes adjacent to a second side edge of the sensing device. Each of the sensor electrodes is configured to be coupled to a routing trace through one of the vias. In a first row of the plurality of sensor electrodes, a two vias are different distances from the first side edge and in a second row of the plurality of sensor electrodes, two vias are different distances from the second side edge.

  • Patent number: 9760222
    Abstract: Embodiments herein include a device, system, and method for periodically capturing sensing signals using one or more detection electrodes to generate data for detecting an object proximate to the detection electrodes. The sensing signals are captured during detection periods within periodic detection cycles where each of the detection cycles define a period of time between consecutive detection periods. In addition, the device, system and method set a duration of the detection cycle to 1/m (where m is appositive integer) of a duration of a display-scan cycle. The value of m is selected based on a periodic noise signal. Thus, the device, system, and method may prevent a periodic noise signal which has a cycle that is longer than the detection period from worsening the accuracy of touch detection.

  • Patent number: 8001870
    Abstract: An accelerator capable of detecting a turning angle of an accelerator pedal with high accuracy includes a bearing part, an urging part, an accelerator pedal, a stopper, and a turning angle sensor. The accelerator pedal has a turning shaft supported by the bearing part and is turned forward when a depressing force is applied thereto and is turned reversely when the urging force of the urging part is applied thereto. The stopper abuts against the accelerator pedal to limit the reverse turn of the accelerator pedal and substantially simultaneously guides the accelerator pedal in a direction equivalent to that which the urging force is applied. The turning angle sensor detects the turning angle of the accelerator pedal.

  • Publication number: 20050075315
    Abstract: The present invention is meant to provide a novel use of benzyl alcohol for an antitumor agent guaranteed to have sufficient safety. The present inventors have made a study on the possible action of benzyl alcohol on a tumor cell to develop the use and a treatment method thereby. As a result, it has been found out that the local administration to a cancer cell site can promote the cancer cell to be separated off very efficiently and specifically. Thus, the usefulness for an antitumor agent is confirmed. Moreover, the combination with an antioxidant has been found out to increase the effect.

  • Patent number: 6867583
    Abstract: A displacement sensor precisely detects displacement of a moving body in a rectilinear movement direction even if the moving body rotates. The sensor includes a detector and a magnet. The cross sectional area of the permanent magnet in a plane perpendicular to an axis, which extends in the rectilinear movement direction, varies in the direction of movement. The permanent magnet is magnetized in the rectilinear movement direction. The detector is located so that magnetic flux passes through a detection face of the detector substantially perpendicularly.

  • Publication number: 20040200309
    Abstract: An accelerator device includes a bearing portion, an accelerator pedal having a cam with a cam shaft that is supported by the bearing portion to be turned forward and reversely by an action of a treading force, a follower that abuts against a cam surface of the cam when a turning position of the accelerator pedal is in a kickdown region, a bias device that generates a biasing force to press the follower against the cam surface, and a turning position sensor that detects a turning position of the accelerator pedal. Further, the biasing force of the bias device is set to act on the follower substantially toward a center of the cam shaft. Thus, the accelerator device can accurately detects a turning position of an accelerator pedal while giving a kickdown feeling to a driver.

  • Patent number: 6289922
    Abstract: A flow control valve having a seating surface formed on a valve element to contact a valve seat when the valve is closed has a shape of a part of a hypothetical spherical surface having a spherical center at a center of a supporting member. Therefore, the distance from the center of the supporting member to the seating surface is kept constant, and the valve element can be seated at a periphery of the valve seat without a gap, even if the shaft is inclined. Thus, the valve leakage is reduced. The supporting member supports a shaft connected to the valve element movable in an axial direction of the shaft. The center of the supporting member is aligned with a center of the valve seat. Movement of the supporting member in a radial direction of the supporting member is prohibited. Therefore, the center of the supporting member is not displaced from the center of the valve seat in the radial direction. Accordingly, the displacement of the shaft in the radial direction can be prevented.
