Optical signalling device (1, 20, 30) for vehicles (A), comprising: a support element (2) fitted to the abovementioned vehicle (A), a revolving element (3) arranged on the support element (2) and coupled to drive means (4) able to cause rotation thereof and one or more optical signalling elements (8) associated with the revolving element (3) and electrically connected to an electric power source able to illuminate them. Each optical signalling element (8) comprises one or more laser light genera...

The invention relates to methods pertaining to cell reselection in a cellular telecommunication system. According to the invention, a connection setup rejection message is used to direct a mobile communication means to attempt a new connection with certain parameter values such as a certain carrier frequency. A plurality of parameter values may as well be indicated in the message, which allows the network to direct the mobile communication means to make a connection setup request to a specific c...

At least one three phase driven pumps (56) in a hydrocarbon well (10) well bore (12) uses frequency shift keyed digital signals (78) to pass instructions from a surface station (46, 26, 34, 30) to a tool (14, 76, 56) and reports from a tool (14, 76, 56) to the surface station (46, 26, 34, 30) in common mode through the three phase cables (16) using a star point (58) of the three phase cables (16) after each pump as the signal transmission and reception point and as the point for coupling a DC Po...

A danger signalling system, including a multiplicity of detectors (M1 to M.sub.n) and other line members, in case of need, which respond to at least one danger criterion and are connected to a two-wire line (line A), a control centre connected to the line (line A), which has a voltage supply and a central processor in which the addresses of the detectors are stored for individually addressing and polling the detectors as well as a program for monitoring the status of the detectors. A testing cir...

The present invention relates generally to a method for regulating cytokine signaling and agents useful for same. The method of the present invention is predicated in part on the identification of the molecular target of suppressor of cytokine signaling (SOCS) interaction in controlling cytokine signaling. The identification of the molecular target permits the development of assays to screen for a range of agonists and antagonists useful in modulating cytokine function. The present invention fur...

A portable traffic signalling device comprises a frame on wheels which supports an enclosed occupant compartment arranged to receive an occupant therein. The compartment is pivotal on the frame between an upright deployed position and a transport position lower in elevation than the deployed position. A traffic indicator is supported on the frame for directing vehicular traffic as controlled by the occupant of the compartment. The device permits a human operator to judge how to direct traffic wi...

A signal device for attracting the attention of a service provider. The signal device has a body with a tapered base adapted to fit into a neck of a bottle and a slot in a lower end of the base for balancing the signal device on a rim of a drinking vessel. An intermittent light source is provided in the top of the body.

The object of the invention is a lighting device for a motor vehicle, comprising a first light source focused on a first reflective zone and a second light source focused on second reflective zone. The first light source is able to emit light both in the direction of the first reflective zone and part of the second reflective zone, the light coming from the light source and reflected by the two reflective zones corresponding to a DRL daylight light beam.

A method of updating a lookup table associated with a TDM transmit unit which is coupled to a packet network to receive data therefrom, the lookup table mapping packet network contexts to TDM channels. The method includes priming a controller with data for updating the lookup table in advance of the receipt of packets containing data to which the update relates, incorporating a flag in each packet sent over the packet network to the TDM transmit unit, the flag being set to indicate whether or no...

Metronomic signalling devices and method for generating and transmitting silent and nonvisible metronomic impulses by sense of touch, i.e., to the skin of a user so that the user thereby receives tempo guidance by feeling the impulses through the skin.
