Patent EP-0318256-A2 (EP)
Inventor: HELFER JEFFREY LAWRENCE C O EA
IPC: B01L3/00
Filed: 1988-11-23
Abstract: There is disclosed a cuvette (30) constructed with an improved sample fluid thermal time constant, featuring a flexible heat transfer wall (34, 34a). To prevent such wall from deforming under pressure generated at high processing temperatures, thereby reducing heat transfer efficiency, the opposite wall (36a) is constructed to have a flexural strength that is sufficiently less than that of the heat transfer wall. This causes flexing to occur in the opposite wall, under pressure, rather than the heat transfer wall.

Title: Tool holder
Inventor: MANSCHITZ ERWIN
IPC: B25D17/08
Filed: 1988-05-04
Abstract: The tool holder, consisting essentially of a guide tube (3) and an adjusting sleeve (6) rotatably mounted thereon, has holding segments (7), of roughly U-shaped design in cross-section, for locking the tool (5). In this arrangement, the legs of the holding segment (7), which are designed as locking elements (7a) and driving strips (7b), engage in longitudinal grooves (5b, 5c) of the tool (5). Either the entire holding segment (7) or only the driving strip (7b) can be disengaged radially by rotating the adjusting sleeve (6). As a result, the holding segment (7) plunges into escape niches (6a) on the inside of the adjusting sleeve (6). The position of the holding segments (7) is controlled by a cam (7c) on the outside of the holding segments which interacts with an inner contour (6b) on the adjusting sleeve (6). A catch with a ball (8) and an annular spring (9) secures the adjusting sleeve (6) in the different rotary positions.

Abstract: A pseudo-static RAM device is disclosed which operates fast in the reading or writing mode and permits a long refreshing period in the self-refreshing mode. In the pseudo-static RAM of the present invention, an activation signal for enabling the sense amplifiers is generated with a variable delay time, from a time point when a designated word line is driven. The delay time is switched to be such a long one in response to a control signal representing the self-refreshing mode that is enough to transfer 100% of the amount of information stored in the designated, driven memory cell to the bit line connected thereto, and is maintained short when the control signal representing the self-refreshing mode is not present.

Abstract: The present invention provides a technique for updating the coefficients a(n) of an adaptive filter impulse response A(n), where 
A′(n) = (a₀(n) a₁(n) . . . a m (n)) 
is the adaptive filter impulse response at time n. The impulse response is utilized for tracking the output y(n) of a communications channel, where      where H is an unknown impulse response of the channel, 
H′ = (h₀ h₁ . . . h m ), 
the ′ character denoting transposition. The channel is driven with a known input signal S(n), where 
S′(n) = (s(n) s(n-1) . . . s(n-m)). 
     According to the technique, the output x(n) of an adaptive filter, where 
x(n) = S′(n) A(n) 
is compared with the channel output y(n) according to the Least Mean Squares (LMS) algorithm to develop an LMS error prediction signal. At the same time, the adaptive filter output x(n) is compared with the channel output y(n) according to the Sign Algorithm (SA) to develop an SA error prediction signal. If the LMS error signal is   greater than or equal to a preselected value, then it is used to update the coefficients a(n) of the adaptive filter impulse response. If the LMS error signal is less than the preselected value, then the SA error signal is used to update the coefficients a(n).

Abstract: In primary switched-mode power supply units or other comparable power electronic circuits without mains transformer, occasionally occurring mains voltage peaks can pose a danger to the smoothing capacitor (7) or the following electronic circuit (8). The overvoltage protection device for an electronic circuit disclosed limits mains voltage peaks to values of the operating direct voltage which are not dangerous. For this, the primary charging current (I) flowing across the smoothing capacitor (7) is determined by means of a current detection device (6). A limit value comparator (10) compares the values (US) detected with a given reference voltage (Uref) and outputs a switch-off signal (A) for opening a semiconductor switch (5) arranged between rectifier (3) and smoothing capacitor (7) if the given threshold value is exceeded. In this manner, mains voltage peaks are reduced to values which are not dangerous with the aid of a switch-on current limiting resistor (4) lying parallel to the semiconductor switch (5). <IMAGE>

Abstract: This invention relates to a microprocessor-based medical pump (10) with a number of manual controls. The operation of this pump requires the attachment of a magnetic label (30) to the front of the pump. This magnetic label includes a given number of strong permanent magnets in a pre-determined configuration which indicate the pharmaceutical product type and concentration to be infused. The magnetic label also changes the visual scales around the manual controls. Hall Effect sensors read the pre-determined configuration and send the data to the microprocessor which also reads the manual controls. Using the pre-determined configuration data and the manual control data, the microprocessor determines the desired infusion parameters.

Abstract: This technique for assembling a print head for an LED printer has LED dice (16) first assembled into precisely known locations on mounting tiles (13). A portion (19) of the front face of each tile (13) is left exposed beyond anything mounted on the tile (13). The tiles (13) are then assembled with these exposed areas (19) on a planar reference (32) on an assembly fixture (31). Reference surfaces (34,36) built into the fixture (31) align the edges of the tiles (13), and hence the LED dice (16). Finally a mother plate (10) is adhesively bonded onto the backs of the tiles (13). The adhesive accommodates thickness variations in the mounting tiles (13), and lack of flatness in the back surfaces of the tiles (13) and the front face of the mother plate (10). Reference tiles (41) coplanar with the reference plane formed by the front faces of the mounting tiles (13) provide a z axis reference.

Abstract: A self-sealing annular filter component for opera­tion within a housing portion of a pyrotechnic inflator device. The filter comprises: (a) first and second ring-­shaped members (56, 58) configured to form an annular frame, at least one of the ring members being provided with at least one tab member (38) formed integrally therewith and extending outwardly therefrom toward the other ring-shaped member to maintain a set spacing between the frame members, and (b) a plurality of filter layers (24, 28, 31, 32, 34, 36) supported upon the filter frame, each filter layer positioned so as to at least partially overlap a preceding underlying filter layer around the entire annular surface of the filter frame. The outer circumferential edge of the ring-shaped frame member is adapted to ensure circular line contact with an inner portion of the inflator housing (12). This causes the filter to be self-sealing against the housing as a result of outwardly directed hoop stresses produced by activation of the inflator and thus ensures that the gaseous combustion products produced as a result of the inflator firing do not bypass the filter and exit directly into an attached air bag.
