Oak Technology was an American supplier of semiconductor chips for sound cards, graphics cards and optical storage devices such as CD-ROM, CD-RW and DVD. It achieved success with optical storage chips and its stock price increased substantially around the time of the tech bubble in 2000. After falling on hard times, in 2003 it was acquired by Zoran Corporation. Oak Technology helped develop the ATAPI standard and provided the oakcdrom.sys CD-ROM driver that was ubiquitous on DOS-based systems in the mid-1990s. Wikipedia.

A system for determining a location of an object on a planar surface includes a time-of-flight sensor having sensing elements that provide a field of view for the time-of-flight sensor. The system also includes a mirror attached to the shaft of a motor for reflecting the field of view of the time-of-flight sensor across the planar surface. The system also includes electrical circuitry configured to receive range images from the time-of-flight sensor as the field of view is swept across the planar surface and process the range images to identify the object in at least one of the range images. The electrical circuitry is also configured to calculate a location of the object on the planar surface relative to the motor based on an angle of the shaft associated with the at least one range image and based on a distance of the object from time-of-flight sensor.

Systems and methods for determining a location of a stylus on a planar surface are provided. In one example, a system includes a first optical source, a second optical source, a stylus, and electrical circuitry. The optical sources are at source locations and configured to rotationally sweep optical beams along the planar surface. The optical beams include encoded data sequences that vary with time. The stylus contains at least one optical receiver and is configured to receive the optical beams. The stylus is also configured to detect the data sequences from the optical beams. The electrical circuitry is configured to determine angular relationships between the stylus and the source locations based on the detected encoded data sequences. The electrical circuitry is also configured to calculate coordinates of the stylus on the planar surface based on the angular relationships and the source locations.

A transponder for facilitating financial transaction communications is provided. The transponder includes a detector, a processing module, and a magnetic field source. The detector detects a first time varying magnetic field generated by a mobile electronic device. The first time varying magnetic field is encoded with financial account information. The processing module decodes the detected time varying magnetic field to recover the financial account information. The magnetic field source generates a second time varying magnetic field for detection by a magnetic read head of a point-of-sale terminal. The second time varying magnetic field is modulated with the recovered financial account information according to a sequence that corresponds to a standardized format for encoding a magnetic strip of a credit card readable by the magnetic read head of the point-of-sale terminal.
