Abstract: The operating status of a plurality of laundry appliances including washing machines (12) and/or driers (13) is sensed, and a controller (205) generates and transmits corresponding status signals to remote transceivers (35) which include visual (45) or audio (46) indicators for indicating the information. Each transceiver (35) can interrogate the controller (205) to determine the status of the appliances (12, 13), with the status being transmitted only to the interrogating transmitter. Each transceiver (35) can also transmit a reservation signal to the controller (205) to reserve a selected appliance for a predetermined period of time. The controller (205) also transmits status signals for the selected appliance only to the transceiver of the user who reserved the appliance when the operating cycle is finished, or at a predetermined period of time prior to the end of the operating cycle. The transceivers (35) can communicate with the controller (205) over a telephone line, or over A.C. power lines (27).

Title: Scheme for label switched path loop detection at node device
Inventor: KATSUBE YASUHIRO
IPC: H04L45/18
Filed: 1998-08-06
Granted: 2003-10-14
Abstract: A node device and a label switched path loop detection method which are capable of detecting a label switched path loop efficiently and quickly are disclosed. In a node device for carrying out the label switching, an ingress node information is included in a message that is to be successively transmitted from the upstream side in order to set up a label switched path, and the fact that the message with the same ingress node information for the same packet flow will be received from a previous hop node that is different from before if the label switched path has a loop formed thereon is utilized. Also, at a time of transmitting a message for the purpose of setting up a label switched path, if a node at which the label switched path for that packet flow already exists on the upstream or downstream side is encountered, this already existing label switched path is traced along the same or opposite direction as the flow, and the label switched path is set up if no loop is detected after tracing to the end.

Abstract: A signal distributing/synthesizing apparatus includes a 4-terminal hybrid circuit, first and second antennas, a pseudo-antenna, and first to third 4-terminal switches.  The 4-terminal hybrid circuit distributes the signal input to the first terminal to the second and third terminals, and synthesizes the signals input to the second and third terminals into a signal to be output to the first terminal.  The first and second antennas form a radio transmission channel for an output signal from the signal 4-terminal hybrid circuit.  The pseudo-antenna forms a pseudo-radio transmission channel for an output signal from the 4-terminal hybrid circuit.  The first switch complementarily switches/connects a first broadcasting unit and the first antenna to the first terminal of the 4-terminal hybrid circuit and the third switch.  The second switch complementarily switches/connects a second broadcasting unit and the second antenna to the second terminal of the 4-terminal hybrid circuit and the third switch.  The third switch complementarily switches/connects the pseudo-antenna and the third terminal of the 4-terminal hybrid circuit to the first and second switches.

Abstract: By using a LAN emulation in an ATM environment, end systems such as workstations etc. can connect to the ATM network while software applications  interact as if they are attached to a traditional LAN. The invention is a simple technique for emulating a LAN on an ATM network. According to the invention, each end system is identified by hub and port identifiers which represent a hub and a port of the hub to which the end system is connected. By labelling each ATM cell, and proper label translation at hubs, a LAN can be emulated without using network servers which would introduce cumbersome extr a procedures.

Abstract: A prosthesis that resiliently engages a body passage includes an annular clamping ring which may be folded along a diametric axis for insertion into the body passage. The clamping ring is adapted to resiliently spring outwardly, once in position inside the body passage, and to be continually resiliently biased against the interior surface of the body passage. One or more of the clamping rings may be attached to opposed ends of a tubular graft. The rings and connected graft may be positioned in the body passage using an applicator which selectively permits expansion and/or in some embodiments contraction of the annular ring in position within a body passage. Alternatively a retaining member may be used to retain the annular ring in a compressed condition until it is in a desired position within a body passage. Among other potential uses, the present invention may be useful as a vascular stent for treating abdominal aortic aneurysms.

Abstract: Location of a remote unit within a wireless communication system is determin ed by utilizing an Amplitude Difference-based Angle of Arrival estimation (AD- AOA). In particular, a prompt ray (401) from a signal (117) having undergone  multi-path scattering is received at multiple antennas (103 and 105). The prompt rays (401) received at each antenna are combined by a signal combiner  and averager (307). The signal combiner and averager (307) then averages the  energy of the summed prompt ray over multiple power control groups to determine an accurate energy level for the summed prompt ray. The averaged energy value for the summed prompt ray is then output to an AOA computer (309), along with the average energy value for summed prompt rays at other sectors. The energy values for the summed prompt rays received from each sector are analyzed to determine an appropriate angle of arrival.
