摘要： An integrated circuit device inductive touch analog front end (AFE) excites selected ones of a plurality of inductive touch sensors, measures voltages across the coils of the plurality of inductive touch sensors, and provides analog output signals representative of these coil voltages. A physical displacement (touch) to the inductive sensor causes the inductance value of the inductive touch sensor to change with a corresponding change in a voltage across the coil of the inductive touch sensor. A digital processor controls selection of each one of the plurality of inductive touch sensors and receives the respective analog output voltage signal from the inductive touch AFE. When a sufficient change in the coil voltage is determined by the digital processor, that inductive touch sensor is assumed to have been actuated and the digital processor takes action based upon which one of the plurality of inductive touch sensors was actuated (touched).

摘要： 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.

摘要： An apparatus for simulating the internal configuration of industry standard ROM and EPROM-type chips using other types of storage technologies, while still operating transparently with interfaces and mechanisms such as authentication devices adapted to EPROM-type media. The invention includes: an EPROM connector interface, a data presentation program; user access log display program; a user login/registration program; a software/data library; software/data selection program; and software/data loader program. These components work in conjunction to securely retrieve software images resident in mass storage media and to present them to an authentication device as if the images were resident in EPROM type media. The invention is particularly adapted to use in the gaming industry where regulation and fraud detection are performed using EPROM authentication techniques.
