Abstract: A node in an optical communications network receives optical packets at its input. It determines a priority assigned to each optical packet. When the optical packet is a transit packet destined for another node then, if the packet is determined to have a relatively higher priority, it is output from the node via a continuous-flow transmission path. Other transit packets havi ng relatively lower priorities are sent via an alternative transmission path th at may include queues or buffers resulting in a variable delay.

Abstract: The disclosure relates to an apparatus for sterilizing a sealed enclosure (1 ) comprising a fan (8) for circulating a gas through a preparation circuit (11 ) and through the enclosure. The preparation circuit includes an evaporation chamber (10) for dispensing a decontaminant gas and water vapour mixture int o the circulating gas to flow therewith through the enclosure and to reach a concentration in the enclosure above the dew point for the ambient temperatu re in the enclosure and thereby to condense onto surfaces in the enclosure to sterilise such surfaces. A monitor (15) measures gas temperature and dew point/condensation are monitored (17, 18) in the enclosure and the resulting signals led to a control module (19) for controlling the rate of dispensing of the decontaminant gas and water vapour into the gas in the preparation circu it in response to the levels determined by said monitoring to provide a require d level of condensation of the decontaminant gas and water vapour in the enclosure.

Granted: 2008-07-08
Abstract: A sheath (20) for use on a closed loop Joule-Thomson cryosurgical probe (10), and the combination of the sheath (20) and the closed loop probe (10). The sheath (20) is slipped over the probe (10), thereby separating the probe from the environment.  The sheath (20) has a grip (22) which fits over the handle (12) of the cryosurgical probe, and an extendible shroud (23) which can be longitudinally extended to cover tubing (18) and which are attached to the handle (12). The sheath (20) has a hollow multi-lumen catheter (24) shaped and sized to fit snugly over the cannula (14) of the cryosurgical probe (10).

Title: Smart solid state relay
Inventor: BRYAN LYLE STANLEY
IPC: H02H9/00
Filed: 2003-02-06
Granted: 2008-05-06
Abstract: An electrical system includes a solid state relay (1) and an electrical connector (2) that connects solid state relay (1) to a load (4). The solid state relay (1) includes a power MOSFET (Q1) for switching power to the load (4). A PNP transistor (Q2) monitors the voltage drop across the power MOSFET (Q1), and shuts the power MOSFET off when the voltage drop exceeds a reference level. The solid state relay circuitry floats when the power MOSFET is commanded OFF so there is no leakage to ground. The relay (1) can be used with an electrical connector that includes a short pin (34) or shunt (16) that is disconnected before male and female terminals (12, 22) are unmated. Disconnection of the shunt (16) or the short pin (34) causes the power MOSFET to be commanded OFF so that there is no current flowing through the male and female terminals (12, 22) when they reach an arc susceptible position. The solid state relay (1) and the connector (2) are suitable for use in a 42 Volt automotive electrical system.

Abstract: A more effective method of automatically milking animals in an automatic milking facility is disclosed. The method includes the steps of (i) assigning a respective threshold value (t.v.) to each of the udder quarters (1st u.q.;  2nd u.q.; 3rd u.q.; 4th u.q.) of an animal to be milked indicating when the milking of the corresponding udder quarter is to be ended; (ii) measuring the milk flow from each udder quarter of said animal during milking; and (iv) ending the milking of an udder quarter of the animal (end1; end2; end3; end4) in dependence on the measured milk flow from that udder quarter reaches the corresponding threshold value. According to the invention at least the threshold value for the udder quarter (4th u.q.) of said animal, for which the ending of milking very last remains, is raised (t.v.115%; t.v.inf; t.v.(t);  t.v.eo) subsequently to the very first ending of milking of an udder quarter of said animal, to thereby shorten the total milking time (tmt) of the animal, and thus more rapidly freeing milking capacity of the milking facility to be used for the milking of a further animal.
