  • Patent number: 7833320
    Abstract: A method and apparatus for removing fine particulate matter from a fluid stream without interrupting the overall process or flow. The flowing fluid inflates and expands the flexible filter, and particulate is deposited on the filter media while clean fluid is permitted to pass through the filter. This filter is cleaned when the fluid flow is stopped, the filter collapses, and a force is applied to distort the flexible filter media to dislodge the built-up filter cake. The dislodged filter cake falls to a location that allows undisrupted flow of the fluid after flow is restored. The shed particulate is removed to a bin for periodic collection. A plurality of filter cells can operate independently or in concert, in parallel, or in series to permit cleaning the filters without shutting off the overall fluid flow. The self-cleaning filter is low cost, has low power consumption, and exhibits low differential pressures.

  • Patent number: 7833879
    Abstract: A spatial light modulator is fabricated by bonding a capping layer over a wafer bearing active reflecting surfaces utilizing a low temperature bonding agent capable of providing a hermetic seal, such as a glass frit. The low temperature bonding agent may be B-stage cured after application to the capping layer, prior to any exposure to the substrate bearing the reflecting surfaces. In accordance with one embodiment of the present invention, the capping layer may comprise a glass wafer pre-bonded with an interposer spacer layer to provide sufficient stand-off between the capping layer and the underlying reflecting structures. In accordance with an alternative embodiment of the present invention, the capping layer may comprise a glass wafer alone, and the bonding agent may include additional materials such as beads or balls to provide the necessary stand-off between the capping layer and the underlying reflective structures.

  • Patent number: 7834302
    Abstract: A laser safety device and method of protecting against harmful levels of radiation. The device includes a housing with first and second apertures. A photodetector generates a first signal corresponding to a level of radiation entering the housing through the first aperture. A control circuit receives the first signal and generates a drive signal based upon the level of the radiation. A reflector array which can include micro-electro-mechanical mirrors receives the drive signal and diverts a first part of the radiation away from an incident path extending from the first aperture to the second aperture. The reflector array allows a second part of the radiation to continue along the incident path at a safe level towards the second aperture. Optionally, the reflector array blocks the incident path so that substantially no radiation passes to the second aperture if unsafe levels are detected.

  • Patent number: 7836116
    Abstract: A linear transform such as a Fast Fourier Transform (FFT) is performed on an input data set having a number of points using one or more arrays of concurrent threads that are capable of sharing data with each other. Each thread of one thread array reads two or more of the points, performs an appropriate “butterfly” calculation to generate two or more new points, then stores the new points in a memory location that is accessible to other threads of the array. Each thread determines which points it is to read based at least in part on a unique thread identifier assigned thereto. Multiple transform stages can be handled by a single thread array, or different levels can be handled by different thread arrays.

  • Patent number: 7835617
    Abstract: According to the invention, techniques for recording data onto recording media at relatively high transfer rates for relatively long periods of time. Embodiments according to the present invention include systems and apparatus capable of an improved sustained rate of data recording onto disk type-recording media, for example. Many embodiments can remove the upper limits of both recording capacity and the number of media that can be used. Select embodiments can be used with different kinds of recording media as well. In a specific embodiment, the area on a hard disk is divided into three areas. A first area can be suitable for sequential recording of continuous data. A second area can be suitable for random recording of discontinuous data. A third area can be used for recording logical sector numbers, coupling logical sector numbers, and file information that are used for marking each of the first and second areas, so that continuous data can be recorded on the hard disk at a high data rate.

  • Patent number: 7834672
    Abstract: A charge pump is configured to control current flow at an output node in response to input signals. A plurality of control signals are generated based upon the input signals. The control signals operate to control the timing and duration of current flows within the charge pump and to thereby reduce charge pump power consumption. Based upon the control signals, the conductivity of a first path between a power supply and the output node and a second path between the output node and a ground potential is varied. Optionally, the charge pump is disposed as part of a phase-locked loop (PLL), the input signals are produced by a phase/frequency detector, and current flow at the output node controls an oscillator element.

  • Patent number: 7833870
    Abstract: A semiconductor device is fabricated having a stack gate structure where a first gate electrode, a second gate electrode and a gate hard mask are stacked. The stack gate structure secures a contact open margin while reducing a loss of the gate hard mask during a self-aligned contact (SAC) etching process of forming a landing plug contact. An intermediate connection layer is formed in a landing plug contact region between the first gate electrodes. Furthermore, the occurrence of a bridge between a gate and a contact can be prevented while forming the landing plug contact. A conductive material is filled into a gate region including a recess between intermediate connection layers to form the first gate electrode. The second gate electrode and the gate hard mask are formed during a gate-patterning process using a gate mask, even though misalignment occurs between the gate and the contact.
