Efficient search window storage schemes for motion estimation in video signal processing are disclosed. According to one embodiment, motion estimation is carried out as follows: allocating a ring buffer to store at least critical number of macro-blocks of luminance data from a reference frame on the motion estimator, establishing a rule to relate each storage unit of the ring buffer with each of the macro-blocks of the reference frame, initializing the ring buffer by reading in one less than the critical number of macro-blocks from the reference frame, when the macro-block is located next to a border of the reference frame, generating one or more added border macro-blocks and storing into the corresponding position of the ring buffer in accordance with the rule, constructing the search window from the macro-blocks stored in the ring buffer, and conducting motion estimation of the current macro-block of the current frame with the search window.

Techniques for transmitting data between devices based on two-dimensional symbols are disclosed, where the devices are generally not equipped with the traditional networking capabilities, or at least these traditional networking capabilities are not used for the data communication. According to one aspect of the techniques, two devices communicate with each other by displaying one or more two-dimensional symbols. Data is encoded into one or more symbols that are displayed on one of the devices. Images of the symbols are taken by another one of the devices to receive the data. These images are sequentially processed and decoded so that the data is now received. To accommodate various environments, the system is configured to adjust parameters pertaining to the symbols to achieve an optimum transmission rate.

A method an apparatus for analyzing biomolecules is described. The method includes injecting and storing one species of ionized molecule in a linear ion trap and injecting second species of oppositely polarity ionized molecule such that the second species is transmitted through the stored first species. The resultant reaction products may be analyzed by a mass analyzed taking account of the remaining charge values. In an aspect, a linear ion trap may be used as the reaction volume, and the ionized species injected along the axis of the trap in a substantially collinear manner. The mass analysis may be performed by mass selective axial ejection or by a mass spectrometer.

A door lock locator configured to attach to a door having a latch edge and to locate the door lock in relation to a strike plate. The door lock locator includes an edge wall having an edge hole locator, a first wall extending from the edge wall and including a bore hole locator, a second wall extending from the edge wall and cooperating with the first wall to attach the door lock locator to the door. The door lock locator also includes a strike plate locator coupled to one of the edge wall, the first wall, and the second wall. The strike plate locator has a protrusion that selectively engages the strike plate to locate the edge hole locator and the bore hole locator.
摘要:
A method and apparatus for radial activation of transmission-mode electron transfer ion/ion reactions using a dipolar AC field applied transverse to a transit direction is disclosed. Increases in fragment ion yields and structural information from electron transfer dissociation (ETD) were observed. The method may be used for transmission mode ETD for relatively low charge states of peptides and proteins.
