| 20110233386 | SINGLE-ELECTRON DETECTION METHOD AND APPARATUS FOR SOLID-STATE INTENSITY IMAGE SENSORS - Embodiments of the present invention include an electron counter with a charge-coupled device (CCD) register configured to transfer electrons to a Geiger-mode avalanche diode (GM-AD) array operably coupled to the output of the CCD register. At high charge levels, a nondestructive amplifier senses the charge at the CCD register output to provide an analog indication of the charge. At low charge levels, noiseless charge splitters or meters divide the charge into single-electron packets, each of which is detected by a GM-AD that provides a digital output indicating whether an electron is present. Example electron counters are particularly well suited for counting photoelectrons generated by large-format, high-speed imaging arrays because they operate with high dynamic range and high sensitivity. As a result, they can be used to image scenes over a wide range of light levels. | 09-29-2011 |
| 20110235771 | CMOS READOUT ARCHITECTURE AND METHOD FOR PHOTON-COUNTING ARRAYS - Embodiments of the present invention include complementary metal-oxide-semiconductor (CMOS) readout architectures for photon-counting arrays with a photon-counting detector, a digital counter, and an overflow bit in each of the sensing elements in the array. Typically, the photon-counting detector is a Geiger-mode avalanche photodiode (APD) that emits brief pulses every time it detects a photon. The pulse increments the digital counters, which, in turn, sets the overflow bit once it reaches a given count. A rolling readout system operably coupled to each sensing element polls the overflow bit, and, if the overflow bit is high, initiates a data transfer from the overflow bit to a frame store. Compared to other photo-counting imagers, photon-counting imagers with counters and overflow bits operate with decreased transfer bandwidth, high dynamic range, and fine spatial resolution. | 09-29-2011 |

| 20080222315 | PROXY ASSOCIATION FOR DEVICES - A first connection is established between a first device and a host, wherein the first device is host-capable. A second connection is established between a second device and the host. Proxy association is performed between the first device and the second device by the host to associate the first and second devices, wherein the first and second devices are unable to directly associate, wherein the host passes association information between the first and second devices. | 09-11-2008 |
| 20090158301 | Multi-function device ID with unique identifier - A computer system that recognizes multi-function devices and associates functions with multi-function devices. Each multi-function device may be represented by a multi-function object, allowing tools, applications or other components within the computer to take actions relating to the entire device or relating to a function based on the association of that function with other functions in the same device. These actions include displaying information about devices, instead of or in addition to information about functions. Actions also include selecting functions based on proximity within a device. Functions may be associated with a multi-function device using a unique device identifier provided by the device or generated for the function based on a connection hierarchy between functions and the computer. Devices may be configured to provide the same identifier regardless of the transport over which the device is accessed. | 06-18-2009 |
| 20090207055 | METHOD FOR PROCESSING DATA QUANTIFYING FORCE APPLIED TO ONE OR MORE KEYS OF A COMPUTER KEYBOARD - A computer receives data from a keyboard having one or more keys which cause generation of keyboard data that quantitatively describe the relative force applied to those keys. The keyboard data are transmitted in an HID report containing identifiers for one or more keys that have been pressed and force data for each key. The force data may be a multi-bit value quantifying the key force, or a null indicator signaling that the key is not force-sensing. Keyboard data messages are then prepared which identify keys pressed, contain force data, and may indicate whether the force data updates previous force data. Force updates are only provided to application programs registering for key force data. In other aspects of the invention, key repeat messages are automatically generated for a key held pressed by a user. The key repeat messages are generated at a rate controlled by the amount of force applied to the key. | 08-20-2009 |
| 20090293070 | DEVICE DISPLAY OBJECT INFRASTRUCTURE - Multi-function devices expose multiple functions to device drivers or other lower-level software. Device function providers can interface with such drivers or lower-level software and can provide information, including device identifiers regarding such functions, to a device display object infrastructure. A device display object can then be created that encompasses one or more functions such that, in one embodiment, the device display object corresponds to a single, physical multi-function device. Alternatively, any combination of functionality from one or more physical devices can be combined into a single device display object representing a virtual multi-function device. Properties of the device display object can be set with reference to user-specified settings, remotely maintained metadata, locally available metadata, and information associated with each function. Functions can be ranked such that, if there is a conflict, information from more highly ranked functions is used to set the properties of the device display object. | 11-26-2009 |
| 20090319660 | GENERALIZED ARCHITECTURE TO SUPPORT REPRESENTATION OF MULTI-TRANSPORT DEVICES - A computer system that accesses multi-transport devices and associates device instances of the multi-transport device with each other. Devices provide the same device identifier such as a device unique identifier regardless of the transport over which the device is accessed. A visual representation for the multi-transport device may be provided to a user using the device identifier. Also, a single functional representation for the multi-transport device may be provided based on an identifier provided by each function of the device. The functional representation may be independent of the addition and removal of transports and allows abstracting device access via multiple transports from a user and an application. Transports may be selected at an application and/or a system level. Operating characteristics of available transports may be used to select a desired transport, based on transport requirements specified by the application, the user or the system. | 12-24-2009 |
