Abstract: A network repeater is configured to repeat data packets in a broadcast mode without generating a significant broadcast storm. The network repeater is configured to detect a characteristic of a received data packet. The data packet characteristic is compared with valid copies of packet characteristics previously stored in a packet registry. During a delay period, if a valid copy of the detected characteristic is found in the packet registry, then it is assumed that the packet is being received for the second time and the data packet is not repeated in the broadcast mode. If a valid copy of the detected characteristic of the data packet is not found in the packet registry, then the characteristic is stored in the packet registry and the data packet is repeated in a broadcast mode.

Abstract: A programmable gain amplifier comprising alternatively selectable parallel circuits in a front end and independently selectable serial amplification circuits in a back end. The front end may include, for example, a plurality of transconductors in parallel and each configured to generate a current proportional to a received voltage. A ratio of the generated current to the received voltage being different for each of the transconductors. The back end is configured to receive an output of a selected member of the parallel circuits and may include a plurality of current or voltage mode amplifiers in series. For example, the back end may include a plurality of current-mode gain stages and switches configured to control which of the current-mode gain stages are used to amplify the output of the front end. The programmable gain amplifier may be used between a signal receiver and an analog to digital converter.

Abstract: Methods and apparatus for direct detection of chemical reactions are provided. In a preferred embodiment, electric charge perturbations of the local environment during enzyme-catalyzed reactions are sensed by an electrode system with an immobilized target molecule. The target molecule is preferably DNA. The charge perturbation caused by the polymerase reaction can uniquely identify a DNA sequence. The polymerization process generates local perturbations of charge in the solution near the electrode surface and induces a charge in a polarazible gold electrode. This event is detected as a transient current by a voltage clamp amplifier. Detection of single nucleotides in a sequence can be determined by dispensing individual dNTPs to the electrode solution and detecting the charge perturbations. Alternatively, multiple bases can be determined at the same time using a mix of all dNTPs with subsequent analysis of the resulting signal.

Abstract: Electromagnetic motor with a slider that moves linearly with respect to the stator in either direction. Embodiments include slider internal or external the stator. Slider includes one magnetic flux producing element in all embodiments. Internal slider embodiments stator includes a minimum of three magnetic flux producing elements and a maximum of four such elements. External slider embodiments stator includes two magnetic flux producing elements. All embodiments provide positive slider return to center at rest position. In internal slider embodiments the slider is centered within the stator resulting from either: a combination of a repelling force from a single magnetic flux producing element in opposition to gravitational pull on the slider due to its weight; or equal and opposite repelling forces on opposite sides of the stator from a magnetic flux producing element on opposite sides of the stator all three elements in longitudinal alignment with each other.

Abstract: Methods and apparatus for remotely measuring temperature of a specular surface. Method takes two measurements of P-polarized radiation emitted at or near Brewster angle from the surface. First measurement (SA) collects and detects first amount of radiation emitted directly from a surface portion using a collection optical system. Second measurement (SB) includes first amount of radiation and adds quantity of radiation collected at or near at/near Brewster angle and reflected from the surface with a retro optical system with a round-trip transmission t2 that retro-reflects a quantity of radiation received from surface portion back to same surface portion where it reflects and combines with first amount of radiation collected by collection optical system. Measurements SA and SB and t2 are used to determine surface emissivity (?). Calibration curve is used that relates ratio of the first measurement SA to surface emissivity (SA/?), to surface temperature.

Abstract: A pre-printed case label is provided for labeling cases that contain item-level packages such as clamshells of produce or loose bulk produce. The pre-printed case label includes a common identifier and space for adding a tag that includes a unique identifier. A case that includes the pre-printed case label and the tag provides case-level traceability through the distribution chain. Additionally, the item-level packages, or items of loose bulk produce, can include their own individual traceability codes to extend the traceability down to the item level. Methods provided herein associate non-lot-specific information, like brand and quantity, and lot-specific information, like harvest event data, with the unique identifier.

Abstract: A method and apparatus for performing laser thermal processing (LTP) using a two-dimensional array of laser diodes to form a line image, which is scanned across a substrate. The apparatus includes a two-dimensional array of laser diodes, the radiation from which is collimated in one plane using a cylindrical lens array, and imaged onto the substrate as a line image using an anomorphic, telecentric optical imaging system. The apparatus also includes a scanning substrate stage for supporting a substrate to be LTP processed. The laser diode radiation beam is incident on the substrate at angles at or near the Brewster's angle for the given substrate material and the wavelength of the radiation beam, which is linearly P-polarized. The use of a two-dimensional laser diode array allows for a polarized radiation beam of relatively high energy density to be delivered to the substrate, thereby allowing for LTP processing with good uniformity, reasonably short dwell times, and thus reasonably high throughput.

Abstract: Methods and apparatuses are provided for positioning a substrate having a target that may be located on either the front-side or the backside of the substrate.

Abstract: Provided is an apparatus for substrate processing. The apparatus may include a radiation source emitting a photonic beam, an optical system to form a beam image, a scanning stage, a temperature monitoring means, an output signal generator that compares the monitored temperature with a preset temperature, and a controller coupled to the radiation source and the stage. The stage may be adapted to scan the substrate so the beam image heats a region of the substrate surface, and the temperature monitoring means may collect and analyzes p-polarized radiation of at least three different spectral regions emitted from one or more places on the heated substrate region. The controller in response to a temperature error signal may be programmed to alter the beam intensity and/or to provide changes in the scanning velocity between the stage and the beam. Other apparatuses and temperature monitoring systems are provided as well.

Abstract: Artificial antimicrobial peptides are obtained by alterations in alpha helical portions of a known antimicrobial protein, granulysin. The peptides obtained have significantly improved antimicrobial activity and lack the ability to lyse mammalian cells, which may be toxic to a host. The peptides may be designed according to certain guidelines, and may further be modified by the addition of altered residues and alterations in normal peptide secondary and tertiary structure, including modifications in quaternary (multimeric) structure.

Abstract: A chuck for supporting a wafer and maintaining a constant background temperature across the wafer during laser thermal processing (LTP) is disclosed. The chuck includes a heat sink and a thermal mass in the form of a heater module. The heater module is in thermal communication with the heat sink, but is physically separated therefrom by a thermal insulator layer. The thermal insulator maintains a substantially constant power loss at least equal to the maximum power delivered by the laser, less that lost by radiation and convection. A top plate is arranged atop the heater module, supports the wafer to be processed, and provides a contamination barrier. The heater module is coupled to a power supply that is adapted to provide varying amounts of power to the heater module to maintain the heater module at the constant background temperature even when the wafer experiences a spatially and temporally varying heat load from an LTP laser beam.

Abstract: Methods for forming a denuded zone in an oxygen-containing semiconductor wafer using rapid laser annealing (RLA) are disclosed. The method includes scanning an intense beam of laser radiation over the surface of the wafer to raise the temperature of each point on the wafer surface to be at or near the wafer's melting temperature for a time period on the order of a millisecond or so. This rapid heating and cooling causes oxygen in the wafer near the wafer surface to diffuse out from the wafer surface. Oxygen in the body of the wafer remains unheated and thus does not diffuse toward the wafer surface. The result is an oxygen-depleted zone—called a “denuded zone”—formed immediately adjacent the wafer surface. The methods further include forming a semiconductor device feature in the denuded zone such as by implanting the wafer with dopants.

Abstract: A method for increasing or monitoring apoptosis in tumor cells by the co-administration of ionizing radiation and an anti-integrin antibody. Increasing apoptosis reduces tumor growth in vivo and in a cell culture model. The antibody is directed against the beta-1 integrin subunit and is inhibitory of beta-1 integrin signaling. Other molecules having an inhibitory effect on beta-1 integrin, either in signaling or in binding to its cognate extracellular receptors may also be used. The present method is particularly of interest in treatment of tumor cells associated with breast cancer, wherein radiation is currently used alone. The present method further contemplates a monoclonal antibody suitable for human administration that may further comprise a radioisotope attached thereto.
