  • Patent number: 11269132
    Abstract: A display device includes a light source arranged to emit light along a first edge of the display device, and aa light guide plate arranged go receive the emitted light at a minor surface of the light guide plate. The light guide plate includes prismatic elements configured to reemit the light out a first major surface of the light guide plate. A first region of the light guide plate has a first portion of the prismatic elements arranged in a first density to provide a first brightness of the reemitted light reemitted. A second region of the light guide plate has a second portion of the prismatic elements arranged in a second density to provide a second brightness of the reemitted light reemitted. The first region is provided substantially along a first edge of the first major surface, and the second region is provided along a second, a third, and a fourth edge of the first major surface.

  • Patent number: 8284249
    Abstract: A method for real time processing of a sequence of video frames. The video frames are received in synchronization with a recording of the video frames in real time for triggering an alert. The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. An algorithm determines whether a static object in a current frame of the video frames is an abandoned object or a removed object. The determined status, the current frame time, the static region, and the static object are stored in a data storage medium of the computer system. An alarm is triggered in response to satisfaction of requirements that include a persistence requirement, a non-persistence duration requirement, and a persistence duration requirement.

  • Patent number: 8107678
    Abstract: A method for processing a time-ordered sequence of video frames. The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. A current frame and at least one frame occurring prior to the current frame in the sequence are analyzed via a background subtraction on the at least one frame to determine a background image and a static region mask associated with a static region. The background subtraction determines an existence of a static object relating to the static region. A status of the static object is determined, the status being either that the static object is an abandoned object or that the static object is a removed object. The determined status is stored in a data storage medium of the computer system.

  • Patent number: 8092778
    Abstract: A method for producing a hydrogen enriched fuel and carbon nanotubes includes the steps of providing a flow of methane gas, and providing a catalyst mixture comprising a Fe based catalyst and carbon. The method also includes the steps of pretreating the catalyst mixture using microwave irradiation and exposure to CH4, heating the catalyst mixture and the methane gas using microwave irradiation at a selected microwave power, directing the flow of methane gas over the catalyst mixture, and controlling the microwave power to produce a product gas having a selected composition and the carbon nanotubes. For producing multi walled carbon nanotubes (MWNTs) only a flow of methane gas into the reactor is required. For producing single walled carbon nanotubes (SWNTs), a combination of hydrogen gas and methane gas into the reactor is required.

  • Publication number: 20080011804
    Abstract: The present invention provides a pill splitter that is designed for cutting pills in a relatively safe and reliable manner. The pill splitter includes a main body with a top housing and a bottom housing having a blade mounted thereto. The top housing has a slot defined therein for receipt of the blade. The top housing moves relative to the bottom housing between a protected position, unexposed blade, and a cutting position, exposed blade. In the protected position, the top housing resides in front of the blade to prevent a user from contacting the blade. In the cutting position, the blade is routed through the slot in the top housing thereby exposing a cutting edge thereof for cutting a pill.

  • Publication number: 20040068656
    Abstract: Systems, methods, and apparatus utilize a smart card as a key to gain access rights to turn on or wake up a device. To turn on or wake up the device, a user may present a smart card to a reader coupled to the device. The smart card reader provides a signal to the device. Upon receiving the signal, the device may then interface with the smart card to authenticate the user. The device may require the user to provide additional information, such as a password or personal identification number. In addition, the device may access another device, e.g., across a network, to authenticate the user. If the user is authenticated, the device may continue with the turn-on or wake-up sequence. If the user is not authenticated, the device may terminate the turn-on or wake-up sequence. In addition, the device may issue an alarm to report a failed access attempt.

  • Patent number: 6170027
    Abstract: A LPC/ISA bridge and its bridging method are disclosed for bridging an LPC interface to an ISA interface. The LPC/ISA bridge is activated in response to a duty cycle indicative signal (LFRAME#), and serially transforms related command, address and data information from command/address/data lines (LAD[3:0]) of the LPC interface into address, data and control signals of the ISA interface. Therefore, the problem as to the interface incompatibility is solved.
