Abstract: An apparatus of the present invention for blowing a cable has a meandering detection section provided adjacent to a feeding rollers. The meandering detection section includes a straight passage for the cable passing therethrough, a recessed portion being arranged on a wall of the passage, and a detector detecting the cable meanderingly entering into the recessed portion. When there is no entering of the cable into the recessed portion, the cable is in the normal insertion condition. On the other hand, when the cable meanders at a short pitch entering deep into the recessed portion, the detector detects the abnormality of the insertion, and the feed speed is controlled to cancel the meandering of the cable.

Abstract: An allergy-diagnosing method comprising analyzing a sample that has been tak en rectally from the large intestine of a patient who is suspected of being allergic, after having provoked the mucous membrane of the patient's large intestine rectally with an allergen against which the suspected allergy of the patient is directed. The method is characterized by: (a) taking the sample in the lumen of the large intestine; (b) determining an inflammation marker in the sample; and (c) taking an elevated marker quantity (elevated release) as an indication that the patient is allergic to the allergen concerned. The invention also relates to an instrument for rectal insertion into the rectum. The instrument is characterized in that it has an expandable part which surround s a central channel that opens out on each side of the expandable part, and a separate channel through which expansion of the expandable part can be controlled such that when the instrument is applied in the rectum, the outer wall of the expandable part will be in direct contact with the mucous membrane of the rectum; and in that a diffusible allergen and optionally also a receptor for an inflammation marker is rare present on the outer defining surface of the expandable part.

Title: Method and system for automatically generating efficient test cases for systems having interacting elements
Inventor: PATTON GARDNER CONDE
IPC: G06F11/28
Filed: 1995-10-10
Granted: 2000-04-18
Abstract: Our method and system for enumerating a minimal number of test cases for systems with interacting elements operates relationships between the elements and the number of characteristics evaluated for each element. In our inventive method as executed in a computer system (16), the user enters values for each of the elements and then defines relationships (18) between the elements. Our method then enumerates a table of test cases (14) for each relationship between elements using deterministic procedures, when applicable, and random procedures when the deterministic procedures are not applicable. After a table of test cases is generated for each of the relation, our inventive method combines (20) relationships into a single table of test cases.

Abstract: An ice pebbler is used for pebbling a sheet of curling ice. The pebbler has a wheel supported base that may be pulled or motor driven across a sheet of ice. The pebbler carries a water container for the pebbling water and a pebbler head mounted on the base for lateral movement across the sheet. The pebbler may be manually operated, pulled by hand and with a hand crank for swinging the pebbler head across the sheet. In the preferred arrangement, the wheels and the pebbler head movement are driven so that the pebbler will travel at a uniform speed along the ice sheet. The swinging movement of the pebbler head may be driven by the wheels or motor driven to provide even greater pebbling consistency. The water pressure may be from a gravity feed or air pressure, but the preferred arrangement is a pressure pump, which delivers constant pressure throughout a pebbling operation.

Granted: 2003-10-07
Abstract: In a packet switching (packet-based) network, such as a frame relay (FR) network, which includes network resources made up of networked elements and customer premises equipment interconnected by one or more physical paths, a Virtual Private Network (VPN) is built above the underlying packet-based network and includes selected portions of the packet-based network resources. The VPN is a collection of logical nodes and virtual paths (VPs) and includes one or more virtual circuits (VCs), each VC being a logical connection between VC terminators including network elements and customer premises equipment. Segments of the VCs are carried by VPs, each VP being a logical connection established between two VP terminators which are located in either network elements or customer premises equipment. One or more VPs are multiplexed on a physical path (PP). Each VP is allocated a positive guaranteed bandwidth (VP-CIR), and each VC on a VP is also allocated a bandwidth (VC-CIR) greater than or equal to zero. Packets of information to be transmitted over a VC are provided with a unique address field to thereby identify the VCs and VPs associated with the YPN over which the packet of information will travel. Congestion control of the network is provided such that congestion control and management are carried out on a per VPN basis, and congestion outside of a VPN's logical domain does not affect the performance of the VPN.

Abstract: A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.

Abstract: A method for processing telecommunications signals to alleviate echo during a voice communication between a local talker and a remote talker comprises the application of circular buffers for near and far end signals to preserve processing time. Overlapping blocks of samples are processed and indexed by incrementing the index over time to generate an array for storing magnitude coherence versus time delay between outgoing and incoming samples. Echo is clipped based on power spectral matching. The clipped echo is replaced with noise fill of at least one of two types, white noise and tonal noise, at an appropriate level. Also, crackle which comprises high energy spikes and a residual echo effect which is low energy, bursty and non-linear may be identified and replaced with noise fill.
