Abstract: An integrated optical coupler includes multiple ports and a beam discriminating element. Optical elements are provided for directing light to and from the ports and the beam discriminating element. These optical elements may include two optical elements created on the same surface of a substrate. All of the optical elements needed for directing the light may be formed on a transparent substrate or on a structure in the optical path bonded to the substrate. The optical elements may output light of the different wavelengths at the same angle or may be dispersive. The beam discriminating element may discriminate on the basis of wavelength or polarization.

Abstract: Automatically dimming rearview mirrors allow a vehicle operator to view a scene generally behind the operator at a reflectivity level automatically adjusted to ambient light and glare levels. An automatically dimming mirror includes a dimming element having a variably reflective surface, the degree of reflectivity based on a control signal. An ambient light sensor is positioned to receive light from a region generally in front of the vehicle. The ambient light sensor outputs a discrete ambient light signal based on the amount of light incident on the ambient light sensor over an integration period. A glare sensor is positioned to view the scene generally behind the vehicle operator. The glare sensor outputs a discrete glare signal based on the amount of light incident on the glare sensor over an integration period. A dimming logic determines an ambient light level based on the ambient light signal. The glare integration period is determined based on the ambient light level.

Abstract: A heater circuit (H) according to the invention comprises a stabilizing power supply (SPS) with a control input (CT) which receives a control signal (Cs) to control the value at which the heater voltage (Vh) has to be stabilized. A timing circuit (TC) generates the control signal (Cs) such that the heater voltage (Vh) has a nominal value (Vhn) in a normal operation phase, and such that the heater voltage (Vh) has a boost value (Vhb) higher than the nominal value (Vhn) during a boost period (Tb) of a start-up phase (Ts). The normal operation phase is defined as the phase during which the heater (HE) is sufficiently hot to enable display of a picture with good quality. The start-up phase (Ts) is the phase during which the display apparatus starts up and the heater (HE) warms up.

Abstract: In a process for the oligomerization of light olefins (e.g. propylene) to more valuable higher olefins (e.g. hexene), the use of a molecular sieve (e.g. SAPO-11) that has been acid washed has shown to provide superior selectivity to, and yield of, the desired product. These benefits are attributed to a reduction in non-selective acid sites as well as an increase in phosphorous content (in the case of SAPO molecular sieves) at the molecular sieve crystallite surface, a probable result of removing amorphous silicon aluminum phosphate acid, silicophosphorous acids, and/or phosphoric acids. Furthermore, this removal is likely accompanied by an increased accessibility of olefinic feed components to the so-called “selective” acid sites within the sieve pores. Post-synthesis acid washing of the molecular sieve has not only demonstrated a narrower carbon number distribution of olefin oligomers, but also improved the linearity of the oligomerized olefinic product slate in general.

Abstract: A wafer transport mechanism is disclosed capable of transferring workpiece cassettes between lot boxes and SMIF pods. The transport mechanism includes a frame having a first support platform on a first side of the frame for supporting a SMIF pod, and a second support platform on a second side of the frame for supporting a lot box.

Abstract: An apparatus for measuring ignition charge signals produced by coils of coil-on-plug devices of an internal combustion engine. A signal detector comprises an insulating substrate having a first conductive planar layer on a first side and a second conductive planar layer on a second side. The first layer is coupled to a signal wire and the second layer is coupled to a ground wire. When the signal detector is held in close proximity to the coil of the coil-on-plug, ignition signals generated by the coil and passing to the plug are detected. The detected signals may be coupled to a signal analyzer for display and analysis. The amplitude of the signal that is output by the signal detector may be adjusted to different coils having different output signal strengths by modifying the ratio of the surface areas of the first layer and the second layer.

A process for increasing the thermal stability of inhibitors such as N,N′-di-2-butyl-N,N′-dinitroso-1,4-diaminobenzene is disclosed. The process comprises adding to the inhibitor a stabilizer such as N,N′-di-2-butyl-1,4-diaminobenzene. The mixture of inhibitor and stabilizer is also used to inhibit polymerization of vinyl aromatic compounds.

Abstract: A circuit for use in a two-way pager of a paging system to transmit voice messages. The circuit includes: a microphone to receive an analog audio signal provided by a user; an analog-to-digital (A-D) converter coupled to the microphone; a memory; a processor coupled to the memory and to the A-D converter; and a transmitter coupled to the processor. The analog audio signals are typically voice messages spoken by the user, which the A-D converter samples and digitizes. The processor stores the digitized voice message in the memory. The user can then transmit the stored digitized voice message through the transmitter, which is processed through the paging system and provided to the intended recipient. In a further refinement, the circuit includes a playback circuit that allows the user to listen to the stored digitized voice message before transmitting the voice message to the rest of the paging system.

Abstract: Amino acid and nucleotide sequences relating to the glutamate dehydrogenase (GDH) enzyme are described. The GDH enzymes described herein were discovered in the alga Chlorella sorokiniana in the form of seven different inducible isoenzymes. These isoenzymes are found in the algae as chloroplast-localized hexamers composed of alpha- and beta-subunits. Plants transformed with nucleotide sequences encoding the alpha- or beta-subunits of the enzyme show improved properties, for example, increased growth and improved stress tolerance. A heterohexamer having both &agr;- and &bgr;-subunits can have higher aminating:deaminating activity ratio than &agr;-homohexamers or &bgr;-homohexamers.
