Apparatus and methods are provided that enable the interaction of low-energy electrons and positrons with sample ions to facilitate electron capture dissociation (ECD) and positron capture dissociation (PCD), respectively, within multipole ion guide structures. It has recently been discovered that fragmentation of protonated ions of many biomolecules via ECD often proceeds along fragmentation pathways not accessed by other dissociation methods, leading to molecular structure information not otherwise easily obtainable. However, such analyses have been limited to expensive Fourier transform ion cyclotron resonance (FTICR) mass spectrometers; the implementation of ECD within commonly-used multipole ion guide structures is problematic due to the disturbing effects of RF fields within such devices. The apparatus and methods described herein successfully overcome such difficulties, and allow ECD (and PCD) to be performed within multipole ion guides, either alone, or in combination with conventional ion fragmentation methods. Therefore, improved analytical performance and functionality of mass spectrometers that utilize multipole ion guides are provided.

An optical power beam transmission systems, with a directional light transmitter and receiver. The transmitter contains an amplifying laser medium, and this together with a retroreflector in the receiver, forms a laser resonator. When lasing sets in, the receiver can extract optical power through an output coupler and convert it to electrical power. The gain medium may be a disc having a thickness substantially smaller than its lateral dimensions. The laser resonator is operated as a stable resonator to ensure safe operation. This is achieved by use of an adaptive optical element, for reducing the diameter of the energy beam impinging on the gain medium, thereby increasing the overlap between the energy beam and the gain medium. As the transmitter-receiver distance is changed, such as by movement of the receiver, the adaptive optical element focal length changes to ensure that the cavity remains within its stability zone.

The disclosed system and methods include a power saving scheduler that maintains timed events in an event table. Each timed event has an associated tolerance period within which the event should begin execution following a trigger, and a timestamp indicating a scheduled execution time for the event. When a device is in a low-power sleep mode, a trigger may wake up the device to a wake state. The power scheduler then accesses the event table of upcoming timed events, and reorders the event table from the event having the shortest tolerance period to the event having the longest tolerance period. Each event for which the timestamp is within the tolerance period as measured from the trigger time is executed. After a plurality of such events are executed, the device may return to the sleep mode.

A splicing-interference-detection aspheric surface shape apparatus using a distorting lens and a method thereof belong to the optical detection technology field. In the invention, an interference detection system, a distorting lens compensation system, a mechanical adjusting mechanism and a computer data processing module are included. The method comprises the following steps of step1, constructing a splicing interference detection apparatus using the distorting lens; step2, dividing a subaperture; step3, removing to a position of the subaperture to be detected and adjusting a distorting lens surface shape or a refractive index according to modeling and interference fringes; step4, carrying out subaperture interferogram acquisition processing; step5, carrying out subaperture backhaul error correction; and step6, carrying out full aperture surface shape splicing. In the invention, the distorting lens and the subaperture splicing interference detection method are combined; the subaperture number needed by full aperture coverage can be effectively reduced and effective areas of each subaperture and an overlapping region are increased; a problem that the overlapping region is small so that splicing precision is influenced is solved.

A VCO (for example, in an FM receiver) includes an LC resonant tank. The LC resonant tank includes a coarse tuning capacitor bank and a fine tuning capacitor bank. The coarse tuning capacitor bank contains a plurality of digitally controlled coarse tuning capacitor elements, each providing a first capacitance value when active. The fine tuning capacitor bank contains a plurality of digitally controlled fine tuning capacitor elements, each providing a second capacitance value when active. To address the practical problem of capacitor mismatch, capacitance overlap throughout the VCO tuning range is created by selecting the first and second capacitance values such that the capacitance value of the fine capacitor bank is greater than the first capacitance value when all of the digitally controlled fine tuning capacitor elements of the fine capacitor bank are active.

A method for regenerating a particulate filter is disclosed. In one example, oxygen is pumped from the intake system of a direct injection turobocharged gasoline engine through a cylinder and into the exhaust system by a compressor.

A system, apparatus and application for providing robots with the ability to intelligently respond to perceived situations are described. A knowledge database is assembled automatically, based on distributed knowledge capture. The knowledge base embodies the “common sense,” that is, the consensus, of the subjects who contribute the knowledge. Systems are provided to automatically preprocess, or “clean” the information to make it more useful. The knowledge thus refined is utilized to construct a multidimensional semantic network, or MSN. The MSN provides a compact and efficient semantic representation suitable for extraction of knowledge for inference purposes and serves as the basis for task and response selection. When the robot perceives a situation that warrants a response, an appropriate subset of the MSN is extracted into a Bayes network. The resultant network is refined, and used to derive a set of response probabilities, which the robot uses to formulate a response.

A CMOS processing compatible germanium on silicon integrated waveguide photodiode. Positioning contacts in predicted low optical field regions, establishing side trenches in the silicon layer along the length of the photodiode reduces optical losses. Novel taper dimensions are selected based on the desirability of expected operational modes, reducing optical losses when light is injected from the silicon layer to the germanium layer. Reduced vertical mismatch systems have improved coupling between waveguide and photodiode. Light is coupled into and/or out of a novel silicon ring resonator and integrated waveguide photodiode system with reduced optical losses by careful design of the geometry of the optical path. An integrated waveguide photodiode with a reflector enables transmitted light to reflect back through the integrated waveguide photodiode, improving sensitivity. Careful selection of the dimensions of a novel integrated waveguide microdisk photodiode system results in reduced scattering. Improved sensitivity integrated waveguide photodiodes comprise integrated heaters.

Discontinuous loop antennas and related components, radio-frequency identification (RFID), tags, systems, and methods are disclosed. A discontinuous loop antenna is an antenna loop structure that includes a discontinuity portion. The discontinuous loop antenna can be coupled to an RFID chip to provide an RFID tag. The discontinuity portion decreases the loop inductance and tag capacitance, thus enabling the discontinuous loop antenna to have significantly larger loop area while still matching the chip impedance, resulting in dramatic increases in near-field sensitivity. Increased near-field sensitivity provides increased power harvesting efficiency during near-field coupling. As one non-limiting example, an RFID tag having a discontinuous loop antenna may achieve significantly more power harvesting from a RF signal than an RFID tag having a continuous loop antenna tuned to the same or similar resonant frequency. The discontinuity portion can be trimmed after fabrication allowing the resonant frequency of the RFID tag to be tuned.
