Patent EP-0372882-A3 (EP)
Title: A timepiece glass assembly and a timepiece
IPC: G04B47/04
Filed: 1989-12-04
Abstract: A timepiece glass assembly (1) is provided having a pair of 
superimposed, spaced apart, transparent glasses (2, 3) held together round 
their peripheries by a holding ring (6) in a manner such as to define between 
the glasses and ring an internal chamber (4). The chamber (4) may contain 
a fluid such as scent or a medicament and movable objects or particles (5) 
for decorative effect. The fluid is allowed to escape to the exterior of the 
chamber (4) via a passage (8) through the holding ring (6) in a manner 
controlled by a semi-sealing ring (10) which closes off the outer end of the 
passage (8). The ring (10) absorbs fluid and allows the scent and/or 
medicament to vaporise therefrom and escape to the exterior of the 
assembly (1) which may be removably attached to any suitable timepiece 
such as a wrist watch.

Title: Fifo memory system
IPC: G06F5/14
Filed: 1990-03-23
Abstract: A FIFO memory system for buffering data 
between two data buses includes a RAM memory (12), 
write and read pointer registers (14, 16), an offset 
generator (16), a programmable offset register (20), 
and a comparator (22). The write pointer register 
(14) stores the address of the next data element to be 
written into the RAM memory (12), and the read pointer 
register stores (16) the address of the next data 
element to be read from the RAM memory (12). The 
offset generator (18) compares the contents of the 
registers (14, 16), and generates at an output thereof 
an offset signal representing the amount of memory 
space occupied. The programmable offset register (20) 
provides a programmed offset signal. The comparator 
(22) compares the offset signal and the programmed 
offset signal, and provides a ready signal when the 
offset signal is greater than or equal to the 
programmed offset signal. In one embodiment, the 
addresses stored in the write and read pointer 
registers (14, 16) are encoded in a minimum change 
code such as Gray code.

Title: Opto-electrical position measuring device
IPC: G01D5/38
Filed: 1991-02-18
Abstract: In this measuring device, the angle scale (4) of a dividing plate (2) is scanned by a scanning unit through the movement of a light beam in two diametrically opposites angle scale ranges (10, 11). In order to compensate wobble errors due to the wobbling of the dividing plate (2), the light beam (9) emanating from a light source (5) impinges outside the angle scale (4) at the point (A') on the dividing plate (2), and then impinges as the light beam (9'), parallel to itself after reflection and deviation by a triple prism (7), at the point of impingement (B') on the angle scale (4) in the first angle scale range (10). The light beam (9') is split by the angle scale (4) into two reflected diffracted beams (9a', 9b'), which reunite in the second angle scale range (11) at the reuniting point (C') on the angle scale (4) after passing through a deflecting prism (6). Since the point (B') of impingement and the reuniting point (C') always lie on the same radius even in the event of wobbling of the dividing plate (2), wobbling errors cannot disadvantageously effect the measurement accuracy (Figure 1).

Title: Cardiac pacemaker with automatic a-v programming for optimization of left heart a-v interval
IPC: A61N1/368
Filed: 1991-07-12
Abstract: A dual-chamber AV sequential pacemaker with the capability of automatically adjusting right heart AV interval to optimize left heart AV interval by compensating for pacing-induced inter-atrial and inter-ventricular conduction delays. Depending on the pacing and sensing action, as determined by the patient's native rate, the predetermined threshold rate and intrinsic AV interval, the pacemaker selects the AV interval. Right heart AV interval is adjusted to compensate for the heart's inter-atrial and inter-ventricular delays. Threshold values are previously estimated, using mean values measured using non-invasive techniques. The pacemaker has a dual phase operating mechanism consisting of an analysis phase followed by a pacing phase. The P wave rate is sensed and compared to a predetermined base rate. If the sensed P wave rate is above the baseline, atrial depolarizations will be sensed by the pacemaker and small number (default = 4) of consecutive native AV intervals will be averaged. If this average is less than a predetermined threshold value, the system will continue in the demand mode, sensing P and R waves. If the average is greater than said value, then the ventricle is paced for n number of times the analysis phase (default = 100 cycles), each followed by a short AV delay (Default = 50 ms) that is intended to compensate for the delay introduced in the onset of left ventricular depolarization after pacing the right ventricular apex. When P wave rate is below the predetermined rate, atrial pacing will occur. During the initial analysis phase, the pacemaker AV interval may be extended to a higher value, say 250 ms, to allow measurement of the native AV interval. At least four AV intervals will be averaged to compensate for possible Wenckebach phenomenon. If averaged AV is greater than, say 220 ms, sequential pacing with AV of 160 ms will take place for 100 cardiac cycles. If averaged native AV intervals are less than 220 ms, atrial pacing with ventricular sensing will be continued with the AV interval set at 250 ms for the next 100 cycles. At the end of either 100 cycle period, another 4-beat analyzing phase is started. Both pacemaker phases (analysis and pacing) are programmable. The 4/100 cycle sequence allows rapid pacing mode corrections under situations such as intermittent block due to exercise or other causes. <IMAGE>

Title: Sample tuning recovery for receivers using viterbi processing
Inventor: BERGMANS JOHANNES WILHELMUS M
IPC: G06F17/10
Filed: 1992-04-15
Abstract: Data receiver in which a received signal is sampled and converted to a digital signal by an analog-to-digital converter (1), the signal samples being detected by means of a Viterbi detector (3). In order to have the sampling effected at the correct instants, these sampling instants are derived from the received symbol values and an error signal which is a metric for a difference between an expected and a recent signal sample. This is effected by means of a multiplier 4, a low-pass filter 5 and a control signal for a controllable clock oscillator (6). For utilizing the energy in a precursor of the received signal, an error signal e(k-1) is used which is obtained at a later instant than the instant at which a provisional decision about the relevant data symbol a/< ANd >(k-2) is made. <IMAGE>
Patent EP-0537855-A3 (EP)
IPC: A23B4/28
Filed: 1992-10-12
Abstract: The invention relates to a device for injecting food products, for instance pieces of meat, with a liquid, comprising: a support for the pieces of meat for injecting; a needle carrier placed above the support and movable in vertical direction; injection needles fixed to the needle carrier and extending downward; feed means for supplying the liquid for injecting to each of the injection needles; and at least one drive mechanism for driving the needle carrier in vertical direction. For uniform distribution of the injection liquid in the meat it is important that during the downward stroke the speed is as constant as possible. To achieve this the mechanism, which converts the rotational drive into a linear movement, must have a number of freely selectable variables. This is achieved in that the drive mechanism comprises a planetary gear wheel system. In preference the planetary gear wheel system comprises a sun-wheel and a planet wheel and the sun-wheel and the planet wheel have the same diameter and the same number of teeth. <IMAGE>
