Abstract: A method (36) for providing a current location (35) of a wireless communication device (24) within a wireless communication network (20) calls for activating an automatic location identification (ALI) process in response to a request from an authorized requesting party. An indicator (106) of the current location (35) is provided to the authorized requesting party via a map-enabled web page (100).

Abstract: A slurry monitoring system is provided. A filter encompasses a filter chamber containing a purge piston. During a monitor operation, the purge piston is retracted, and slurry enters the filter chamber through the filter, then passes into an outlet pipe, where a characteristic of the slurry is monitored by a monitoring device. During a purge operation, a flush valve is opened to allow water to pass into the filter chamber through an inlet pipe. The purge piston is extended to force filtered slurry from the filter chamber. The water dilutes filtered slurry remaining in the filter chamber. The flush valve is then closed and the purge piston retracted. This forces diluted slurry to pass out of the filter. This purges the filter. Diluted slurry also passes into the outlet pipe, which purges the outlet pipe and monitoring device.

Abstract: A method (36) for providing location information of a wireless communication device (24) within a wireless communication network (20) calls for determining the coverage areas (26) of particular cell sites (22) through which the device (24) communicated during past calls. These coverage areas (26) are defined as the approximate location information for the device (24) and are provided to an authorized requesting party via a map-enabled web page (156).

Abstract: A HE0&ggr;&dgr; mode dielectric resonator (12) includes a cylindrical dielectric disk (32) having top and bottom ends (20, 22) spaced apart by a closed curve wall (24). The dielectric disk (32) has a dielectric constant greater than 40. An axially aligned hole (36) is formed through the disk (32) between the top and bottom ends (20, 22). A conductive wall (34) is formed at the closed curved wall (24) but not the top and bottom ends (20, 22). The hole (36) has a preferred diameter less than 0.2 times the diameter of the disk. A tuning plug (30) is formed from a material having a dielectric constant less than 0.5 times the dielectric constant of the dielectric disk (32) and an unloaded quality factor greater than 2.0 times the unloaded quality factor of the dielectric disk (32). The tuning plug is inserted to a desired depth within the hole (36) of the dielectric disk (32).

Abstract: A time division multiple access digital communications system (12) is provided. The system (12) has a base station (14) configured to generate a receive baud clock (86) and has a receiver (18) and a transmitter (20). The system also has a subscriber unit (16) configured to generate a transmit baud clock (50), and has a transmitter (28) and a receiver (26). The subscriber unit transmitter (28) is configured to transmit a reverse channel signal (54) that incorporates the transmit baud clock (50) as a component thereof. The base station receiver (18) is configured to receive the reverse channel signal (54) from the subscriber unit (16) and produce a phase-error signal (&mgr;′) in response to a phase difference between the transmit baud clock (50) and the receive baud clock (86). The base station transmitter (20) is configured to transmit the phase-error signal (&mgr;′) to the subscriber unit receiver (26).

Abstract: A vehicle for collecting debris from a road includes an operator cab located at a front section of the vehicle, a boom assembly located at the front section, a paddle guide assembly located at the front section, and a collection bin located at a back section of the vehicle. The boom assembly carries a rotary rake, a leader blade, and a conveyor belt assembly. The operator cab and boom assembly are configured such that an operator has a substantially unobstructed view of the debris as it is being collected. The paddle guide assembly includes a plurality of paddles configured to move the debris into the path of the rotary rake. The rotary rake guides the debris over the leader blade and onto the conveyor belt assembly. The conveyor belt assembly transports the debris into the collection bin.

Abstract: A system and method for counting vehicles by detecting RF signals emitted from a portion of the vehicles is provided. An RF scanner/receiver located at a testing site is tuned to receive local oscillator (LO) signals that may be emitted from radio tuners located in a portion of the vehicles. A control unit controls the scanner/receiver, stores data related to the received LO signals, and performs other operating procedures. A central computer in data communication with the control unit performs data translation operations on the raw LO signal data. Scale factors derived from calibration formulas are applied to the system data to provide an estimated vehicle count and an estimated average vehicle speed. The central computer formats the resulting data for presentation to a user.

Abstract: An antenna (26) projects a detection zone (28) across a non-intersection portion (16) of a road (10). A scanning receiver (32) couples to and is controlled by a data logging computer (34). This computer (34) commands the receiver (32) to look for one FM local oscillator (LO) signal (22) that may be emitted from within the detection zone (28). If one LO signal (22) is detected, other LO signals (22) that may be detected at the receiver are ignored until the one signal is no longer detectable (90-106). An attenuator allows LO signals 22 emitted from radios (20) in the detection zone (28) at noisy frequencies to have the same likelihood of being detected as LO signals 22 emitted at less noisy frequencies. Detected LO signals (22) are ignored if they are detected for less than a minimum duration (100) or if they are detected for greater than a maximum duration (118).

Abstract: An apparatus for determining the reliability of crystallographic solutions of a specimen includes an electron beam generator, a stage for holding the specimen, an image collection system for obtaining diffraction images of crystals within the specimen, and processor for processing the diffraction images to obtain most probable indexing solutions for the crystals and to generate confidence factors associated with the most probable indexing solutions. The apparatus may utilize the confidence factors to determine the phase of the crystals within the specimen. The confidence factors may also be incorporated into reports representing the statistical confidence of various crystallographic characteristics of the specimen.

Abstract: A training apparatus that indicates the alignment of a practice golf stroke includes a base plate and a club member. The base plate includes a body, a pointer, a guide strip, and a warning background. The club member attaches to a golf club, and includes a mounting clip, an extension arm, and a colored translucent blade coupled together. The guide strip, warning background, and blade cooperate to indicate a first color when the practice stroke is aligned and a second color when the practice stroke is misaligned. The apparatus is configured such that a golf ball travels over the practice surface during use, and such that a user can clearly view the golf ball in the address position and as it is struck by the golf club.
