Abstract: An information band for mounting an electrically conductive circuit, such as a radio-frequency identification (RFID) tag. The band comprises a base strip and a top strip. A single sheet of label stock can include a plurality of such bands such that the sheet can be passed through a conventional printer to accept printed indicia onto a surface of one or more bands. These bands can be die cut to facilitate individual removal. The top strip can be either integral with the base strip or a separate piece that can be affixed to a surface of the base strip. Once indicia has been printed to the band, the RFID tag may be manually affixed between the base strip and the top strip, where adhesive disposed therebetween secures the RFID tag. The adhesive may be peripherally deposited such that an adhesive-free zone is formed between the two layers so that when the RFID tag is attached, it does not come in contact with the adhesive.

Abstract: An airhandling unit for an HVAC system includes a cabinet having an electric motor driven centrifugal blower disposed therein. The blower includes a scroll or volute type blower housing which may be formed of opposed releasably connectable housing parts. The blower housing parts include opposed sidewalls with axially extending compound curved portions which cooperate with an end wall which is configured to have portions which are not of substantially constant increasing radial distance from the blower impeller axis of rotation. However, a constantly increasing airflow cross-sectional flow area is provided within the blower housing for blower discharge air. The disposition of the blower housing sidewalls with respect to the cabinet walls provides improved airflow distribution for air flowing into the blower air inlet openings.

Abstract: An air handling blower housing for an HVAC system is formed by two opposed housing parts which are each fabricated of a compression molded reinforced thermoset polymer composition. The housing parts are joined along a parting line, preferably perpendicular to the axis of a motor driven impeller mounted within the housing by wedge shaped clips which engage cooperating bosses aligned with each other when the housing parts are joined. The construction of the housing parts provides for an improved method of assembly of an air handling blower of a type particularly adapted for HVAC systems.

Abstract: An improved two-phase refrigerant distributor for use in a falling film evaporator in a refrigeration chiller system defines apertures in its undersurface from which serrated collars depend. The serrations cooperate to define locations below the undersurface of the distributor to which liquid refrigerant is drawn prior to exiting the distributor. As a result, the hang-up and/or travel of liquid refrigerant on the distributor undersurface is reduced or eliminated.

Abstract: A linerless label is provided, that can be easily imaged, printed, or hand written upon by the end user. The label consists of a single ply, dispensed usually in a roll form, or alternatively, in a stacked form. A label roll is formed from a web of ply. The face of the web is stripe coated with an adhesive repellant release coat. The back of the web of ply is stripe coated with adhesive. Upon winding the web of ply into a roll, the adhesive on the back of the web of ply overlies the adhesive repellant stripes on the face of the web therebelow. The regions of the face of the web of ply not striped with adhesive repellant form areas for user printing and handwriting. Further, any portion of the face of the web of ply may be press printed prior to the application of the adhesive repellant stripes. Likewise, a label stack includes a plurality of label sheets superposed one on top the other.

Abstract: A system may include a memory configured to store an attenuation waveform and control logic. The control logic is configured to receive a synchronizing signal indicative of an operating characteristic of a noise source. In response to a value of a characteristic (e.g., frequency) of the synchronizing signal, the control logic is configured to output the attenuation waveform from the memory if the attenuation waveform is associated with that value of the characteristic of the synchronizing signal. An attenuating noise generated dependent on the attenuation waveform attenuates a noise generated by the noise source.

Abstract: The subject of the invention is an effect pigment which is coated with surface-modifying agents, wherein the initial pigment has a layer with at least one reactive surface-modifying agent, wherein the surface-modifying agent is a compound which has at least two functional groups which are different from each other and which are spaced by a spacer, chemically bound to the initial pigment. Also described is a process for the production of an effect pigment of that kind.

Abstract: An oscillator circuit. In one embodiment, the oscillator includes a gain circuit, an envelope detector, and an amplitude comparison circuit. The trans-conductance circuit is configured to amplify a periodic signal produced by a crystal. Amplitude peaks of the periodic signal may be detected in the envelope detector, which may determine an average amplitude value based on the detected peaks. The average amplitude value may be compared to a DC voltage value in an amplitude comparison circuit. The DC voltage value may include both a DC average of the periodic signal as well as a predetermined DC offset value. The gain circuit may adjust the level of amplification of the periodic signal based on a feedback signal in order to ensure that the oscillator produces a periodic output signal at a desired level so as to insure oscillation and the minimum use of current to achieve oscillations.

Abstract: A low-power phase detector with differential output may comprise a control signal generator. In one embodiment, two cyclic waveforms whose phase relationship is to be measured may be input to a control signal generator. The control signal generator may output a first control signal corresponding to the first cyclic waveform such that the control signal is de-asserted at a specific point with respect to the first cyclic waveform. For example, the control signal may be de-asserted corresponding to the rising edge of the first cyclic waveform. The control signal generator may also output a second control signal corresponding to the second cyclic waveform such that the control signal is asserted at a specific point with respect to the second cyclic waveform. For example, the control signal may be asserted corresponding to the falling edge of the second cyclic waveform.

Abstract: A microwave frequency standard is provided which allows for miniaturization down to length scales of order one micron, comprising a modulated light field originating from a laser that illuminates a collection of quantum absorbers contained in a micro-machined cell. The frequency standard of the present invention can be based on all-optical excitation techniques such as coherent population trapping (CPT) and stimulated Raman scattering or on conventional microwave-excited designs. In a CPT-based embodiment, a photodetector detects a change in transmitted power through the cell and that is used to stabilize an external oscillator to correspond to the absorber's transition frequency by locking the laser modulation frequency to the transition frequency. In a stimulated Raman scattering (SRS) embodiment, a high-speed photodetector detects a laser field transmitted through the cell beating with a second field originating in the cell.

Abstract: The present invention provides a radio controlling apparatus that performs a change to a vacant channel rapidly to allow smooth control even if an uncontrollable state due to radio interference suddenly occurs. In a radio controlling transmission apparatus of the radio controlling apparatus, a reception section for searching a vacant channel is provided. When a vacant channel is detected, it is stored in memory of the radio controlling transmission apparatus. A transmission section transmits control signals, a selection code, and vacant channel data, the control signals being output by an operation section using a control signal transmission timer and a selection code transmission timer. Using a reception section, a controlled apparatus of the radio controlling apparatus receives signals. If the vacant channel data and the selection code are received, the controlled apparatus stores them in memory of the controlled apparatus.

An appropriate gift card form can be printed at a time after manufacturing to allow a vendor to personalize the gift card. Additionally, order information, such as billing information, can be printed on the gift card form at the same time that the gift card is personalized. The gift card form can be kept as a record with the order information.
