Abstract: A telemetry system (10) and method of monitoring cardiac activity or providing therapy to the heart for an implantable cardiac device (12). The system includes a receiver (44) and a transmitter (46) in an external programmer (14) and a receiver section (32) and transmitter section (34) in the cardiac device (12). The receiver section (32) and the transmitter section (34) of the cardiac device (12) generally remain in a de-energized state. The receiver section (32) is energized at spaced apart time intervals to detect an initiation signal transmitted by the external programmer (14). If the initiation signal is detected, the receiver section (32) and the transmitter section (34) of the cardiac device (12) are fully activated. The external programmer (14) includes a signal strength indicating means (242) for providing an indication of received signal strength which the user can use to position the receiver (44) and transmitter (46) in the external programmer (14) for optimum received signal strength. An antenna (36) is disposed in the header of the implanted device to facilitate communication at high speed.

Abstract: The invention relates to the preparation of amides, particularly alkanolamides an gluconamides and to cosmetic or cleaning compositions containing said amides. These are known as lather boosters but contains 1-10% of the corresponding amine. This unwanted component gives a characteristically 'fishy' amine smell to products, can lead to yellowing and can lead to undesirable bi-product formation on storage. It is desirable that these disadvantages are avoided. Our solution involves a selective reaction for amine which does not substantially effect the hydroxyl function. In one aspect of the present invention the amine is reacted with ethylene oxide in the absence of a basic catalyst to form the tertiary amine. Consequently, the present invention provides cosmetic or cleaning compositions comprising amide surfactants where the ratio of the amide to the corresponding amine is greater than 800:1 and the ratio of unethoxylated amide to the corresponding ethoxylated amide is greater than 1:1.

Abstract: A technique for ejecting droplets using acoustic radiation and electrostatic attraction. Ejection proceeds by acoustically raising a mound (14) of ink (18) proximate an electrode (20) and then electrostatically attracting the mound by applying a voltage to the electrode. The electric field further accelerates the mound and, since the raised mound has a restricted volume, a Rayleigh instability necks off the mound, thereby creating a droplet (12). The droplet is ejected onto a recording medium (34) by the momentum imparted to the droplet by the acoustic energy and the electrostatic force. Beneficially, the applications of the acoustic energy and the electrode voltage are used to address the ejecting droplet ejector. Droplet ejectors in a column (or row) form a column (or row) of mounds, while an electrode voltage is applied to each of the electrodes of a row (or columns) of droplet ejectors. Only the droplet ejector associated with an acoustically raised a mound and with an energized electrode ejects a droplet.

Abstract: 2.1. The pressure locks based on engagement into the spokes of the back wheel particularly and padlocks and pivoting-shackle, steel-cable and chain locks are easily accessible from outside and are therefore easy to eliminate or put out of operation by means of a suitable tool. The new safety device is to be of difficult access and simple and robust in construction and mode of operation and is therefore to afford increased safety. 2.2. Fastened preferably in the seat tube of the bicycle frame, near the pedal-bearing shaft reinforced with a bead-like thickening and provided with depressions, is a guide sleeve which has an adjusting member which can be actuated via the lock cylinder of a cylinder lock and of which the rotation as a result of the locking of the lock puts a locking bolt, arranged axially displaceably in the guide sleeve, under spring pretension in the direction of the pedal-bearing shaft and presses it into a depression of the pedal-bearing shaft located opposite the locking bolt. 2.3. The safety device is suitable for ladies' and mens' bicycles of the customary types and sizes. <IMAGE>

Abstract: An improved memory system for a shared memory multiprocessor computer system in which one or more processor modules and/or input/output modules have cache memories (50, 52, 54). The main memory controller (14, 16) for each main memory (15, 17) of the system maintains a duplicate cache tag array (44, 46) containing current information on the status of data lines from that main memory that are stored in the cache memories (50, 52, 54). Thus, coherency checks can be performed directly by the main memory controller (14, 16). This eliminates the need for each processor having a cache memory to perform a separate coherency check and to communicate the results of its coherency checks to the main memory controller, and thereby reduces delays associated with processing coherent transactions.

Abstract: In a method of manufacturing a sliding member, a granular spraying material is sprayed on at least a part of a surface of a body portion made of a structural material in at least partially fusing condition and in the direction which is parallel to or diagonal to a sliding surface. Then, a sprayed layer is formed by depositing the spraying material in the direction which is perpendicular to the sliding surface. The sliding surface is a section of the deposited spraying material which is obtained by grinding or cutting the sprayed layer in depositional direction. A piston comprises a piston body having a broad groove which is broader than a ring groove, a sprayed layer comprising a lower sprayed layer which is formed by spraying the spraying material in the direction which is diagonal to an outer periphery of the broad groove and which contains higher ratio of spraying particles having low fusion temperature, and an upper sprayed layer which is formed by spraying the spraying material in the direction which is perpendicular to the outer periphery of the broad groove and which contains higher ratio of spraying particles having high fusion temperature, and a ring groove which is formed by grinding or cutting the upper sprayed layer in depositional direction. Therefore, excellent wear resistance and the like can be obtained.

Abstract: In a device used to inspect substrates visually, an imaging region and a magnification are specified ahead of time for every component and stored as library data in a memory (23). The memory (23) also contains CAD data, which include the class of each component on the substrate and its location. During initialization, a control unit (22) links the location data for a component extracted from the CAD data to corresponding library data and specifies a field of view and a magnification for every component on the substrate. Using this data, the control unit (22) creates on the substrate a number of viewing zones to be inspected at various magnifications and stores the data specifying these zones in the memory (23). When a substrate is to be inspected, the control unit (22) uses the data specifying these zones to control the position and magnification of an imaging unit (2) to collect image data from each zone successively and display them on a monitor (6).
