摘要:
An apparatus and method for accurately determining a target distance in adverse weather conditions utilizing both LASER and RADAR is disclosed. The radar signals are used to determine an approximate range which is then used as a gating window for the determination of which laser reflection is from the actual target as opposed to a reflection from the atmospheric interference. The method basically comprises the steps of initiating a radar pulse in the direction of a target and receiving a reflection, transmitting a laser signal and receiving a plurality of reflections, determining an approximate range based on the radar signals, and using this approximate range to ascertain which of the laser reflections is from the target. This determination is preferably made by generating a gating signal and gate width from the radar signals and passing the set of laser range signals through the gate to eliminate the false signals and select the signal that survives the gate as the accurate target range.

An example system includes a display, a communication circuit, a memory storing a shopping program, and a processor in communication with the display, the communication circuit and the memory. The processor is configured to execute the shopping program to access a product database including product information, to process inputs supplied to the system to generate a shopping list comprising one or more products from the product database and to provide guidance information on the display relating to product location in a store of the products on the shopping list.

A method of porting a video game or other application from one platform to another involves decompiling the game executable to develop source code in a high level programming language such as C. The (re)generated source code is re-linked using target native libraries to handle hardware functions (e.g., video, audio, etc.) for the target platform. The resulting “trans-compiled” executable is able to efficiently run on the target platform, potentially providing orders of magnitude speed performance boost over other traditional techniques.

A HVAC controls system for zone controls that is comprised of one or more Wall Sensor Units (WSU) and zero or more Damper/Register Units (DRUs). The invention is a low networked cost solution for residential and light commercial that is easy to install in new and existing building. The WSUs detect, log and use occupancy data to predict where in a building HVAC conditioning is needed and to save energy where it is not needed. The DRU use shape memory alloy wires to control the opening and closing of a damper plate with very little power allowing batter operation.

A handheld wireless device is adapted to function as a lightweight, small, and low-cost wireless server for serving handheld wireless clients. The handheld wireless server includes a battery that powers the server, data processing circuitry, read/write memory, and a memory port for receiving an external, detachable, long term, read/write storage device. The read/write storage device stores multiple dynamic server applications for execution by the data processing circuitry and multiple dynamic client applications for download to handheld wireless client devices. Wireless communications circuitry broadcasts initial information and detects communications from handheld wireless client devices including requests to download one of the client applications stored on the long term storage device. The data processing circuitry processes, in parallel, multiple download requests for client applications from multiple handheld client devices, retrieves the client applications from the long term storage device, and provides the client applications wirelessly to the multiple handheld client devices. An example application for traveler in a travel environment is described.

Multiple video game players access an encrypted video game library stored on a shared mass storage device. A multiplexer multiplexes data read from the mass storage device to provide output streams to multiple video game playing units consuming video game instructions. A secure bus communicates video game instructions from the shared mass storage device to each of the video game playing units. Video game software or other entertainment content is distributed to the shared mass storage device via electronic download in multi-level encrypted form. Before being transported, the content is encrypted and then further encrypted. Once the content has been successfully transported, it is decrypted to remove the further encryption layer—leaving the first encryption layer intact for protecting the video game during storage on mass storage at the remote distribution location.

In one or more embodiments, a vehicle safety system includes a processing unit configured for use in a vehicle. The processing unit includes or is associated with one or more vehicle sensors, such as object detection sensors, and one or more cameras. The processing unit processes vehicle sensor signals to detect vehicular events of interest, such as potentially hazardous operating conditions, and in response it selectively activates recording by one of one or more cameras mounted on the vehicle. For example, during lane changing or lane departure events, the processing unit may activate one or more cameras to capture a visual record of objects in the vehicle's vicinity, or may activate recording responsive to object detection, e.g., leading vehicle detection or front, back, side, top object proximities. Further, the processing unit may tailor recording control based on its particular operating mode, or in response to manual input.

StackTrace refers generally here to an apparatus and computer method for use with multitasking operating systems (OS's) such as WINDOWS.RTM.95. StackTrace allows a program to again become responsive to OS messages after the program freezes. A user can then save work which was not yet saved at the time the program froze. In one mode, StackTrace identifies a special signature that appears in the virtual stacks of certain kinds of programs. This special signature is a consistently-used return address to a standard-for-type calling function of the OS. StackTrace locates the special signature in the virtual stack of the frozen program and then changes values stored in context registers of the frozen program to cause a return through the in-stack signature location as would have happened if the halted program function had successfully completed. StackTrace then initiates multitasked processing of the program so that the program will return by using the in-stack signature location. This enables the program to become responsive to messages from the OS.
