Each page can comprise locations for a plurality of photographs. Selectors can be provided for selecting one of the photograph locations on the selected page. Telephone numbers of persons or places depicted in photographs on the pages can be stored in a digital memory. A telephone call can be initiated to a particular person or place by selecting the page and photograph location on the page of that person or place.

Abstract: Energy beams with different wavelengths or wavelength ranges may be passed through a gas sample in a test chamber. Ones of the energy beams may have wavelengths or wavelength ranges that are absorbed by particular gases. To determine whether any of those particular gases are in the gas sample, the loss of energy, if any, as the beams pass through the gas ample may be determined. The presence of one or more gases that do not absorb the energy beams may be determined by placing a chemical reactant that reacts with those one or more gases and then detecting a chemical reaction between the chemical reactant and the gas sample.

Abstract: A system for detecting and remediating a discharge of fuel from a fuel source facility is disclosed. The system can comprise a contamination detection subsystem configured to detect a discharge of fuel from the fuel source facility and a remediation subsystem configured to remediate contamination due to the discharge of fuel. A controller can automatically activate the remediation subsystem upon detection of a discharge by the contamination detection subsystem. The controller can automatically send a notification that a contamination has been detected and the remediation system has been activated. Alternatively or in addition, the controller can automatically send a notification that a contamination has been detected and the remediation system has been activated.

Abstract: A method and system for programming a magnetic memory is disclosed. The method and system further include turning on a word line current and turning on a bit line current. The word line current is for generating at least one hard axis field. The bit line current is for generating at least one easy axis field. In one aspect, the method and system further include turning off the word line current and the bit line current such that a state of the at least one magnetic memory cell is repeatably obtained. In another aspect, the word line current is turned off after the bit line current is turned off.

Abstract: The present invention relates to an improvement in the clearances 12 between a casing and the moving blades 11 of a rotor 1 of a turbomachine, in particular a casing provided for this purpose, and also to a turbomachine fitted with such a casing. The invention applies in particular to aircraft turbojet engines. It relates more particularly to a turbomachine inner casing 21 comprising a plurality of annular shrouds 23 that are provided with flanges 24 for joining two adjacent shrouds 23 together. According to the invention, this inner casing 21 further includes: at least one circumferential heat shield 5 covering the flanges 24 in contact with two adjacent shrouds 23; and a cavity 6 filled with a first thermal insulation 8, said cavity being located between a concave internal surface 51a, 52a of the heat shield 5 and the flanges 24. The heat shield 5 is formed by a plurality of sectors 50 joined end to end.

Abstract: The present invention is a blood separation system that is fully mechanized to collect blood from a patient, separate waste portions of the blood, wash the blood, and redirect the usable portions to a device for reinjecting the usable portions into the patient. The present invention prevents accidental activation of an improper operation that could cause harm to a patient or a shut down of the system by requiring confirmation of each step by an operator. The invention provides screen displays with detailed setup instructions, eliminating the need for secondary documentation that might not be allowed in a surgical environment. The invention also instructs the operator at the appropriate times to do certain manual steps such as opening and closing clamps. Since the opening and closing of clamps is a highly critical operation, confirmation of these steps is also required.

Abstract: A time slot interchanger (10) includes a D-channel processing device (30). The D-channel processing device (30) includes a main memory (32), a D-channel memory (34), and a D-channel assembler (36). The main memory (32) receives telephony data and signaling traffic from a subscriber in the form of integrated services digital network signals. Two-bit D-channel signaling portions of each integrated services digital network signals are extracted and placed into the D-channel memory (34). The D-channel assembler (36) assembles the two-bit D-channel signaling portions into eight-bit digital signal level zero (DS0) signals. The eight-bit DS0 signals are stored in the D-channel memory (34) for subsequent transfer with selected telephony data traffic from the main memory (32) over a synchronous optical network link.
