Abstract: A method for preventing co-channel operation with a radar system includes the steps of setting a state of a first communication channel to active, connecting to a first wireless access point on the first communication channel, passively scanning at least a second communication channel for communication from a second wireless access point, setting a state of the second channel to active if frames are received on the second channel, determining whether an elapsed time since frames were received on at least one of the first channel and the second channel has exceed a predefined value, and in response to the predefined value being exceeded for at least one of the first channel and the second channel, setting the state of a corresponding one of the first channel and the second channel to passive.

Abstract: A method for preventing radio frequency (RF) link failures in a radio telecommunication network. The network includes at least one base station (402) and at least one subscriber unit (SU) (406) which are capable of sending and receiving RF link signals. The method provides for monitoring the RF link between the base station (402) and the SU (406) and determining if the RF link is failing (216), and if so, taking corrective action to maintain the RF Link. The method provides for storing information about the RF Link failure and the corrective action taken (224) and utilizes the corrective action taken in prior RF Link failures to prevent future RF Link failures. The method provides for determining that an old corrective action for improving the RF Link channel quality no longer improves the RF Link channel quality and, therefore, provides for discarding the old corrective action in favor of a new corrective action (234).

Abstract: In the present invention, the subscriber unit (200) obtains a set of access point identifiers and measurement opportunity information for each access point identifier. A first measurement is performed on a first access point identified from the set of access point identifiers. A current timer value is determined after completing the step of performing, and a second access point identified from the set of access point identifiers in which to perform a second measurement is selected. Selecting the second access point is based on at least the measurement opportunity information for the second access point in relation to the current timer value.

Abstract: A method of providing RF signal quality information which includes the step of a probe request generator (110) monitoring a channel for probe requests being transmitted by a station (115) and/or probe responses being transmitted by an access point (105). The probe request generator can determine a time period between the successive probe request transmissions received from the station or successive probe responses received from the AP. The probe request generator can generate a series of probe requests (150) having the determined time period between successive probe request transmissions. The series of probe requests signal an access point (105) to transmit probe responses (155) which are detectable by the station.

Abstract: A wireless station (114) is within range of more than one access point (120, 124) transmitting on the same channel. The wireless station is associated with one access point and not the other. Consequently the wireless station may receive undesired beacons (304) and desired beacons (302) on the channel. To optimize power save operation the wireless station arbitrates between a scan and shut down scanning procedure (708) and a timed window channel scanning procedure (724), depending on whether the desired beacon is the first received beacon upon waking up from a low power state at a target beacon time.

Abstract: A system for presenting meteorological information uses a browser interface to access massive amounts of weather-related data in the form of images stored on the server-side of the system. A user having a common browser on a Web client accesses the server-side information to selectively assemble weather-related data on multiple overlays of images and/or graphics into one simultaneous presentation on a Web page. The different overlays are normalized with respect to time and space, and a user can separately generate graphically miniaturized presentations of weather-related data for saving and subsequently recalling each presentation, wherein each presentation is displayed with current relativized data. The user can also select or customize derived variables to be distinctively displayed as part of a presentation.

Abstract: A processor (1104) receives a baseband signal including a plurality of symbols, and determines (1002) a maximum modulation level and a minimum modulation level in the baseband signal through a modified self-organizing map clustering technique. The processor initializes (1008) a plurality of clusters (700, 800) corresponding to the plurality of modulation levels, based upon the maximum and minimum modulation levels; and processes (1010), through a modified adaptive k-means clustering technique, a symbol value corresponding to each of the plurality of symbols by updating (1012) parameters maintained for a cluster of the plurality of clusters, the cluster having a cluster mean value within a modulation-specified distance from the symbol value. The processor calculates (1014) a plurality of statistical values from the parameters maintained for the plurality of clusters, and classifies (1016, 1018, 1020) the baseband signal, based upon the plurality of statistical values and the parameters.

A cutter is mounted for rotation on each bearing shaft and includes a plurality of cutting elements arranged in generally circumferential rows on the cutter. Each cutter and bearing shaft has substantially zero offset from geometric center of the bit body. A nozzle or drilling fluid orifice is carried generally in the geometric center of the bit body to discharge the gaseous drilling fluid from the bit body to the bit exterior.

Abstract: A device (10) for correcting for the out-of-level condition of a weighing apparatus (20), which includes a scale (22) and a clinometer (24) to provide an accurate weight measurement of a load disposed thereon whenever the tilt of the scale (22) is within preselected out-of-level angles. The device (10) is configured such that the scale (22) and the clinometer (24) provide respective analog weight (23) and angle (60) signals to an analog-to-digital ratiometric converter (70) which generates a proportional digital output signal (72) to a microcomputer (40) for storing the weight in memory (42) and visually displaying the weight on a weight display (48).

Abstract: An optical component assembly is created with reduced defects in the adhesion and alignment between the optical components. A first rigid optical component is placed into a cavity. A second rigid optical component is placed into the cavity such that it is supported by a first support device which prevents a first end of the second rigid optical component from contacting a corresponding first end of the first rigid optical component. Air is evacuated from a chamber formed between the first and second rigid optical components. The support of the first support device is removed so that the first end of the second rigid optical component comes into contact with the first end of the first rigid optical component with a layer of adhesive material sandwiched therebetween. A force is applied to urge surfaces of the first and second rigid optical components toward one another to improve adhesion between the two.

Abstract: A quiver for safely storing and transporting hunting and target arrows including a symmetrically shaped two piece housing with means for selectively storing arrows and foam in the end of each section for preventing relative movement of the arrows. The two sections of the housing are joined by a rail and grove arrangement whereby the ends of the sections form a staggered interface, allowing convenient access to the arrows. A harness attached to the quiver allows it to be carried over the shoulder or in the hand as desired. When the quiver is joined and locked it is highly resistant to moisture and dampness.
