Title: Debris blower
Inventor: HASSKAMP SCOTT
IPC: F04D23/00
Filed: 1999-03-01
Abstract: A debris blower for use in dispersing and collecting grass clippings, leaves, and other debris from sidewalks, driveways, lawns, golf courses and other ground surfaces. The debris blower is designed to be connected underneath a chassis of a tractor or lawn mower, and includes a housing containing a power-driven fan which rotates in a plane generally parallel to the ground surface. An air flow generated by the fan exits the housing through first and second chutes projecting from the housing. The chutes direct the air flow towards the ground surface. Air flow through the chutes is controlled by deflectors and closures that are moveable to selectively open and close the chutes and to adjust the direction of the exiting air flow.

Title: Direct sampling global positioning system (gps) receiver
Inventor: KEEGAN RICHARD GERALD
IPC: G01S1/00
Filed: 1999-09-10
Abstract: A direct sampling technique for use in global positioning system (GPS) receivers, in which received signals are separated into two frequency bands centered at frequencies L1 and L2, respectively, and are then digitally sampled using analog-to-digital converters (24.1 and 24.2) controlled by sampling clock signals derived from a common clock signal generator (26). The clock signal generator frequency and the digital sampling frequencies are selected to provide a sampled carrier frequency that is as low as possible without resulting in a spread spectrum with components in both a positive and a negative frequency region of the spectrum, thereby preserving the real-valued nature of the signal samples. For L1 at 308F and L2 at 240F, where F=5.115, a common clock frequency of 8.5F satisfies these requirements by providing aliasing sampling rates of 306F and 238F, respectively, with L1 and L2 both having sampled carrier frequencies of 2F.

Title: Optical filter for display panel
Inventor: SATO HIROKI
IPC: H01J29/89
Filed: 1997-10-02
Abstract: An optical filter comprising a filter substrate (11) and a transparent conductive film (12) for cutting off electromagnetic waves and infrared rays (for example, a transparent conductive film sputter film), provided on the filter substrate (11) by alternately forming silver thin films and zinc oxide thin films into a multilayer structure. The transmissivity of image light outputted from a PDP (1) is a predetermined value (e.g. 60 %) or more and the surface resistance of the transparent conductive film (12) is 3 .OMEGA./cm2 or less. In this way, the cutoff quantity (damping) of electromagnetic waves of a frequency of 30 to 130 MHz leaking from the PDP (1) is a predetermined value (e.g. 10 dB) or more, and the transmissivity of infrared rays of a wavelength of 800 to 1,000 nm radiated from the PDP is predetermined value (e.g. 10 %) or less. Accordingly, the leakage level of electromagnetic waves leaking from the PDP (1) is below a restricted value, and interference with the operation of remote controllers, optical communication equipment, etc., disposed nearby is prevented by cutting off infrared rays radiated from the PDP (1). When warp of the filter substrate (11) (when it is a synthetic resin substrate, for example) due to heat generated by the discharge of the PDP (1) is a problem, the filter substrate (11) is made of glass (e.g. reinforced glass substrate) to prevent degradation of display quality due to the warp of the optical filter. When corrosion of the transparent conductive film (12) (particularly, a silver thin film) due to the water vapor in the open air is a problem, this corrosion can be prevented by covering the exposed surface of the transparent conductor film (12) with a moisture-proofing film. An AR film (13) is used to prevent reflection of external light so as to prevent the drop of contrast, and an AN film (14) is used to prevent the occurrence of Newton rings (bright and dark concentric circles).

Title: Temperature compensated power detector
Inventor: SADOWSKI ERIC
IPC: H03L7/18
Filed: 2000-02-17
Abstract: A temperature compensated power detector generally comprises a detector circuit portion, which includes a detector diode, and a temperature compensation circuit portion, which includes a temperature compensation diode, that is operably connected to the detector circuit portion. The detector diode and the temperature compensation diode are connected in DC series with each other and develop substantially identical voltage drops. The detector circuit portion operates to detect a voltage from a power input. However, the detected voltage is subject to alteration due to temperature variations. The temperature compensation circuit portion develops a voltage that is also subject to alteration due to temperature variations. The temperature altered voltage of the temperature compensation circuit portion is used to cancel out the temperature altered voltage of the detector circuit portion allowing the power detector to produce a true voltage output.
