20080311877DETERMINATION OF WIRE METRIC FOR DELIVERY OF POWER TO A POWERED DEVICE OVER COMMUNICATION CABLING - A method of powering from a power sourcing equipment to a powered device over communication cabling, the method comprising: determining the effective resistance between a power sourcing equipment and a powered device; determining the length of communication cabling between the power sourcing equipment and the powered device; calculating a metric of the constituent wires of the communication cabling between the power sourcing equipment and the powered device responsive to the determined effective resistance and the determined length of communication cabling; and setting current limits for the powering of the powered device from the power sourcing equipment responsive to the calculated metric. In one embodiment the metric is one of a cross-sectional, an effective resistance per unit length and a current carrying capability of the constituent wires.12-18-2008
20090156159COMMUNICATION SYSTEM AND METHOD IN SHIP AREA NETWORK - The present invention relates to a communication system and method in a ship area network. In a network of a structure including a plurality of shielded regions, communication is performed between terminals provided in the shielded region by using wireless communication, and communication is performed between terminals provided in different shielded regions by further using power line communication, optical communication, or the power line communication and the optical communication in addition to the wireless communication. Therefore, it is possible to obtain advantages of minimizing inconvenience, which is caused by using only wire communication in the related art, and enlarging a working area.06-18-2009
20110183642POWER LINE COMMUNICATION APPARATUS AND POWER LINE COMMUNICATION METHOD - A power line communication apparatus is provided with an auto gain detector that detects a gain fluctuation of an AGC (Auto Gain Control) circuit that automatically adjusts a gain of a received signal; a retry ratio calculator that calculates a ratio of retry based on output from an ARQ (Automatic Repeat request) unit that detects an error in the received data and issues a repeat request; and a transmission rate calculator that calculates a transmission rate based on output from a channel estimation unit that calculates a CNR so as to estimate a transmission status. A display displays a transmission status, including the detected AGC noise fluctuation, retry ratio, transmission rate and the like.07-28-2011
20080214140POWERED PATCH PANEL - A powered patch panel (PPP) is disclosed that inserts power in mid-span regions of a network and provides fault-tolerance at the power supply level and the power-plane level. Information such as physical location, port status and policy enforcement information may be locally stored and utilized by a processor of the PPP to achieve network control and monitoring. A network management system and/or element management system may be provided to interface with processors of PPPs to achieve network monitoring, control and policy enforcement goals.09-04-2008

20090054116Method and apparatus for scent dispensing - A scent dispenser is integratable into a portable device, such as a mobile handset. The scent dispenser has a vibrating element configured to vibrate in an ultrasound frequency range for dispensing a scent material. Scent dispensing can be in response to an incoming signal received by a mobile handset, but scent dispensing can also be controlled by a user. The scent material is stored in a compartment having a channel with a valve and the vibrating element can be used to open the valve for replenishing the scent material when the vibration is in a low frequency range such as 1-10 Hz. The vibrating element can also be used to produce audio signals. Thus, the scent dispenser can also be integrated with a sound producing unit in a mobile electronic device.02-26-2009
