Interleaving Imaging Device Controller With Multi-Use Circuitry
US Patent:
2003010, Jun 5, 2003
Filed:
Oct 15, 2002
Appl. No.:
10/272442
Inventors:
Keiichiro Hyodo - Los Gatos CA, US
Peter Johnson - San Mateo CA, US
Allan Hessenflow - Los Gatos CA, US
Peter Johnson - San Mateo CA, US
Allan Hessenflow - Los Gatos CA, US
International Classification:
G06F003/12, G06F013/00, G06F015/00
US Classification:
358/001130, 358/001150
Abstract:
An imaging device with an improved controller is disclosed wherein the controller eliminates duplicated circuitry and provides multi user circuitry that efficiently replaces multiple dedicated circuit blocks. In one aspect, duplicated same-function circuit blocks are replaced with a switch controlled by an alignment control signal to operate as a multiplexer or demultiplexer. In another aspect, multiple different-function circuit blocks which generally have no temporal overlap of their active operation are replaced with a programmable logic device that is reconfigured dynamically to perform some subset of the different functions on an as-needed basis.
Removing Click And Friction Noise In A Writing Device
US Patent:

International Classification:
G09G 5/24
US Classification:
345179, 401195, 401 52, 347109
Abstract:
Systems for removing or attenuating friction and/or click noise generated during writing with a smart pen are disclosed. In a smart pen, the writing cartridge is biased towards a first side of the smart pen internal cavity by a low-force biasing system without affecting writing cartridge movement. For example, the writing cartridge is comprised of a magnetic material and a magnet is embedded into the first side of the smart pen internal cavity to bias the writing cartridge towards the first side. Alternatively, the material comprising the writing cartridge or smart pen internal cavity is modified, reducing friction between the components. As another alternative, a DSP method identifies analyzes one or more parameters of received audio data to differentiate click noise from audio data, and may receive data from a movement sensor indicating when the writing cartridge has moved to reduce power consumption for identifying click noise.

International Classification:
G06F 1/26
US Classification:
713300
Abstract:
At least two devices are provided that can each form part of a system to inductively exchange power and data. One device is capable of inductively transmitting a power signal to a second device, and to receive feedback from the second device in order to regulate the power signal.
