Abstract: The bath consists of an infrared light source (Q), which is equipped with preferably rod-shaped infrared emitters (S). A first reflector (R1) of parabolic form effects an irradiation which impinges approximately vertically on the area of the body facing towards the infrared light source (Q). Further reflectors (R2, R3) provide for as uniform as possible an irradiation from the side. This arrangement ensures that at least 50%, but at most 90%, of the body surface of the user is irradiated. So that the intensity of radiation is so great that sweating occurs but there is no unpleasant heat sensation, a control which can be activated by the user is preferably provided. An IR-B and an IR-C filter block that fraction of the IR radiation which would cause an increase in the temperature of the interior of the body. A further filter blocks the visible region of the radiation spectrum to the extent that only bright-orange light is visible. The IR radiation can be readily supplemented with UV radiation. <IMAGE>

Abstract: In the apparatus, one switch (1a-1c) is provided for each phase (R,S,T), via which a first input variable (UR, US, UT) of this phase (R,S,T) is in each case supplied to an evaluating unit common to all phases. Each switch (1a-1c) is controlled by modulators (2a-2c). In this arrangement, the active power is measured when the switch (1a-1c) of each phase (R,S,T) is driven by the modulators (2a-2c) with a duty ratio which corresponds to the difference between the duty ratios derived from the two input variables (IR, IS, IT) of the two other phases (R,S,T). This makes it possible to measure reactive power without phase-rotating elements. <IMAGE>

Abstract: To permit adjustment of back parts of the chair, spring means, preferably in form of two U-bent spring rods, couple a lower back part (19) to an upper back part (21) and the effective spring length of the springs (23) is adjustable or changeable by moving a slider (27, 29), connected to one (21) of said back parts, for example via an attachment arrangement (23) of the spring elements themselves, longitudinally of the spring elements. Preferably, a positive stop arrangement to maintain an adjusted position is provided; or the adjusted position may be infinitely variable, for example by clamping the spring element in position by means of an eccentric. The ultimate deflection of the respective back parts can be limited by a stop (36) engaging a stop rod (47') which, simultaneously, can function as a slider guide, the stop rod (47), when springy itself, providing for a stiff terminal spring constant while permitting more easily yielding deflection before its engagement.

Abstract: A container with superposed drawers (12, 14) such as is used as office furniture. The intention, on the one hand, is to provide the possibility to pull out more than one drawer, but on the other hand to prevent the container as a whole from tipping forwards due to the load of the pulled-out drawers. At least one floor roller (16) is arranged on the underside of the bottom drawer (12) near to its front end. Attached to the underside of the "upper" drawer (14) above it are downwardly projecting carriers (46) for the bottom drawer (12), which carriers each bear at their lower end a support roller (44). The support rollers run on the upper edges of the side panels (48) of the bottom drawer (12). When the upper drawer (14) is being pulled out, the bottom drawer is carried along by its carriers (46) and the floor roller (16) supports the front end of the bottom drawer and, via the support roller (44) also the front end of the upper drawer so that the container is prevented from tipping forwards. In order to ensure that the bottom drawer is also carried along by the upper drawer when it is pushed in again, both drawers can be locked together by a latch (32), the latch being ineffective when the drawers (12,14) are pushed in and only becoming effective when the bottom drawer is being pulled out. It is also possible for more than two drawers located above one another to be mutually locked and supported. <IMAGE>

Abstract: A modulation circuit is used in a GMSK modulation system. The system includes I-channel (210) and Q-channel (212) ROM look-up tables, each preprogrammed for generating a representative digital waveform based on an input data stream (250) and a clock signal (252). Each digital waveform is converted to an analog signal for subsequent radio frequency (RF) modulation. Each ROM is addressed by an interpolation counter (224) controlled by the clock signal (252), by a data shift register (226) receiving the input data (250) at a rate corresponding to the clock signal, and by a quadrant register (230), also receiving the input data for specifying the phase of the data signal with respect to the clock signal. Additionally, a signal (242) indicating the arrival of a non-integer bit interval is provided. In response to this signal, ROM addressing is updated in order to provide control of the modulated carrier's phase angle.

Abstract: A method is disclosed for combined cardiac pacing and defibrillating with an implanted pacer/defibrillator having sensing and pacing leads connected to the atrium and the ventricle. P-waves and R-waves are sensed, and a V-V timer and a V-A timer are reset if an R-wave is sensed. If an R-wave is sensed during the V-V timer interval, a pacing stimulus to the ventricle is inhibited. If a P-wave is sensed during the V-A timer interval, a pacing stimulus to the atrium is inhibited. If an R-wave is sensed during the V-V timer interval, arrhythmia therapy is provided if an arrhythmia is determined to be present. If the sensed ventricular rate is greater than a selected tachycardia rate but is less than a selected fibrillation rate, then a determination is made whether the sensed atrial rate is greater than a selected fibrillation rate, and if so, the V-V and V-A timers are reset, but if the sensed atrial rate is not greater than a selected fibrillation rate, then arrhythmia therapy is provided. If an arrhythmia is present, the charging of a capacitor commences but if the arrhythmia ceases, the charging discontinues. If the capacitor is charged and the arrhythmia is still present, then a shock is delivered to the heart during a time period that is outside the vulnerable zones of the atrium and the ventricle.
