Abstract: In a method and apparatus for screening drilling fluids to remove entrained debris, the fluid is urged upwardly from the lower side to the upper side of an inclined or horizontal mesh screen, so that debris falls from the face of the screen under gravity to be collected and removed, and the clean fluid emerges above the screen. The debris may be removed by a conveyor or by a vibrating mesh surface. The operating life of the screen is thereby extended.

Abstract: Measurements of frequency and/or phase are taken at the signal ports (S1-S4) of an ISS device (10). These measurements are used to determine phase errors within the ISS device, and phase errors due to the antenna cables (C1-C4). On port, (e.g., S1) is selected as the reference port and then, based on these determined phase errors, offsetting phase errors are determined to correct the phase for the other ports (e.g., S2, S3, S4) with respect to the reference port. The signals at the antenna ports (A1-A4) are then in phase when an omnidirectional antenna pattern is desired from the TCAS antenna array (16). One in embodiment the frequency of the calibration signal is fixed; in another embodiment two different, fixed frequencies are used; and in still another embodiment the frequency is swept to achieve a predetermined measured phase difference.

The insulation means (10) are formed by one or more flexible ribbons which form a partial insulation barrier between the electrodes and the upstream end (6A). The invention further relates to overload and short-circuit protection devices.

Abstract: An apparatus for coupling and sealing tubes, comprising a flexible duct having a first and second end portions, each portion having an outwardly extending seal portion connected to a flat portion, which in turn is connected to an angled portion which connects to a flat portion having expanded diameter. The apparatus also comprises a sealing assembly comprising a split ring, a compression ring and an end cap subassembly which fits over the compression and split rings. The end cap subassembly comprises a pair of half-rings which are hinged together at one end and latched together using a closure mechanism at the other end. The split ring is mounted over the duct end seal after a tube with a bead is inserted inside the duct. A compression ring is fit over the split ring and the end cap subassembly is latched in place over the compression and split rings, thereby placing the duct seal portion under compressive pressure against the tube and maintaining it in place in a sealed relationship.

Abstract: A circular truncated cone-shaped cutting section (3) of a chamfering tool (1) is formed with a first blade section (31) which is tilted so that a chip is discharged to a side of a shank section (2), and a second blade section (32) which is tilted so that the chirp is discharged to a direction opposite to the side of the shank section (2) in a peripheral direction with a gap. The chamfering tool (1) is rotated, and the first blade section (31) and the second blade section (32) are alternately brought into contact with an edge of an object to be worked so that the edge is chamfered. As a result, occurrence of a secondary burr on the edge is suppressed.

Abstract: The invention provides a circuit breaker panel with several safety features. The main breaker is separated from the circuit breakers by a non-conducting shield. The main breaker is also covered by a transparent, non-conducting shield. A further transparent non-conducting shield separates the circuit breakers from the neutral and ground bus bars. The neutral and ground bus bars are offset from one another to prevent wire crowding. Bending posts extending from the back plate of the panel help control the wire in the panel to prevent it from crossing bus bars or circuit breakers.

Abstract: An alarm system (100) to wake sleeping occupants in the event of an emergency has a receiver (105) for detecting a warning signal (130) emitted from an external device (125), such as a smoke or carbon monoxide detector. A processor (11) compares the received warning signal to a predetermined signal and, if they correspond, then a transmitter (115) transmits an alarm (135). The predetermined signal can be preprogrammed or it can be learned by alarm system. The alarm is at least one of an audible, visual, vibratory, and/or olfactory communication. A customized audible communication in a voice familiar to the occupants can be recorded and stored in the alarm system. In addition, the system may provide different alarms before and after motion is detected.

Abstract: An arrangement where a transmitter has a plurality of transmitting antennas that concurrently transmit the same symbol, and where the signal delivered to each transmitting antenna is weighted by a factor that is related to the channel transmission coefficients found between the transmitting antenna and receiving antennas. In the case of a plurality of transmit antennas and one receiving antenna, where the channel coefficient between the receive antenna and a transmit antenna [I] i is hi, the weighting factor is hi* divided by a normalizing factor, ?, which is ( ? k = 1 K ? ? ? h k ? 2 ) 1/2 , where K is the number of transmitting antennas. When more than one receiving antenna is employed, the weighting factor is 1 a ? ( gH ) H , where g =[g1. . . gL), H is a matrix of channel coefficients, and ?is a normalizing factor ( ? p = l L ? ? ? q = l L ? ? ? ? k = l K ? ? h p ? ? k ? h qk * ? ) 1/2 .

Abstract: An interactive education tool for graphically representing components of a complex system. When the user selects a displayed component of the system, the tool provides educational information relating to the selected component. A user may then “drill-down” further into the display of the system in order to obtain additional information regarding the selected component.

Abstract: A system for locating a device in a wireless network that caches a known location and sets an expiration time based on the location. The system correlates the location with known places, such as movie theaters, restaurants, etc. to set the expiration time. For example, if a device was known to be at a movie theater, the expiration time would be set to a longer period of time. However, if the device was determined to be in a moving location, the expiration time would be set to a shorter period of time. The system also includes a mechanism to query the cached location based on a current time of the query and a granularity variable the accounts for a geographic area in which the device is located. The system also accounts for special locations where the mobile device will likely not be moving for long periods of time, or locations where the mobile device may move great distances between determinations of actual location.

Abstract: An attribute rule enforcer for evaluating the attributes of a call to add, modify, or delete information in a directory, such as a lightweight directory access protocol (LDAP) directory. The attribute rule enforcer determines if the attributes of the call comply with predetermined rules governing the directory's content. The directory attribute rule enforcer may be located at the front end of the directory's access server, and intercepts calls to the directory access server. If the directory attribute rule enforcer determines that the attributes of a call complies with the rules governing the content of the directory, it will forward the call to the directory's access server for action. If, on the other hand, directory attribute rule enforcer determines that the attributes of a call do not comply with the rules governing the content of the directory, the attribute rule enforcer will reject the call. Further, it may forward an appropriate error message to the source of the call.
