International Classification:

A47D 1/10

US Classification:

2972501

Abstract:

A child restraint system includes a belt assembly for restraining a child occupant and a control unit for monitoring proper adjustment of the belt assembly. The belt assembly may include a belt harness affixed to the child restraint system or a vehicle belt seat. The child restraint system also includes a sensor for detecting the presence of the child occupant, a sensor for determining whether the belt assembly is properly adjusted, and a sensor for determining whether the vehicle is in motion. The control unit provides an alert signal if the child is present, the vehicle is in motion and the belt assembly is not properly adjusted.

Assignee:

Microchip Technology Incorporated - Chandler AZ

International Classification:

G02F 1/13357
H04M 99/00

US Classification:

362 23, 362 24, 362 973

Abstract:

Backing lighting of induction touch keys is accomplished with a spacer layer surrounding an inductive touch sensor coil and a light source on a substrate, and light transmissive layer having a suspended metal disk proximate to the inductive touch sensor coil. A protective fascia may be placed over the light transmissive layer and spacer layer. When the light transmissive layer is displaced toward the inductive touch sensor coil the impedance value of the inductive touch sensor coil changes and the change is detected. Materials used that are translucent (light transmissive) may be continuous and solid, and opaque materials may have openings therein for transmission of light therethrough.

International Classification:

B60G 17/005

US Classification:

280005502

Abstract:

An arming signal for enabling deployment of rollover safety devices by a vehicle rollover detection apparatus is based on an off-axis measure of vehicle acceleration. A low-g accelerometer mounted perpendicular to the longitudinal axis of the vehicle but at an angle with respect to Earth's ground plane detects components of both lateral and vertical vehicle accelerations. The measurement angle is selected to apportion the lateral vs. vertical measurement sensitivity in accordance with calibrated lateral and vertical acceleration thresholds, and an arming signal is generated when a filtered version of the measured acceleration exceeds an arming threshold.

International Classification:

G06F 3/044

US Classification:

345174, 178 1806

Abstract:

Systems and methods for determining a user's touch in a capacitive touch sensor system is provided, including performing a series of potential touch detection tests for a plurality of sensors until a potential touch is detected and measuring a test frequency for one of the sensors, such that a potential touch may be detected when the measured test frequency deviates from a previously measured test frequency for the same sensor. After detecting a potential touch, the method may additionally include performing a series of baseline comparison tests for each of the sensors, for example, measuring a current frequency for one of the sensors, comparing the current frequency to a baseline frequency, and assigning a deviation value based on the comparison the current frequency and the baseline frequency. The method may identify the sensor with the largest deviation value as a touched sensor.

International Classification:

G06F 3/045

US Classification:

345174

Abstract:

A multilayer printed circuit board provides both physical and electrical attributes necessary for creating an inductive touch sensor panel. Inductive sense coils are formed on a surface of first layer of the multilayer printed circuit board. A second layer is used as a spacer between the first layer and a third layer. The first, second and third layers of the multilayer printed circuit board form chambers in which the inductive sense coils are disposed therein. When a force is applied to a portion of the third layer proximate to an inductive sense coil, a metal target on a face of the third layer is biased toward the inductive sense coil and thereby changes the inductance value thereof.

International Classification:

H03K 17/975

US Classification:

200600

Abstract:

A physical force capacitive touch sensor comprises a capacitive sensor element on a substrate, a physically deformable electrically insulating spacer over the capacitive sensor element and a conductive plane over the physically deformable electrically insulating spacer. A protective fascia may be placed over the conductive plane provides an environmental seal for physical and weather protection, but is not essential to operation of the capacitive touch sensor. Back lighting is accomplished with a light transmissive layer having a suspended metal target proximate to the capacitive touch sensor plate. When the light transmissive layer and metal target are displaced toward the capacitive touch sensor plate the capacitance value of the capacitive touch sensor plate changes and that change is detected.

Inventors:

Dan Termer - Phoenix AZ, US

International Classification:

H01F 5/00

US Classification:

336200

Abstract:

An inductive touch sensor comprises an inductors disposed in or on a deformable substrate. When a force is applied to the deformable substrate the physical shape of the inductor will change and thereby change its inductance value. The change in the inductance value can be detected and used to indicate actuation of an associated touch key of the inductive touch sensor. A plurality of inductive touch sensors may be used to form a touch panel.
