摘要： A scale including an event data discrimination and collection system for continuously monitoring a weight of an infant placed on the scale platen, which may be configured as a bed. Load cells are used to continuously monitor infant weight from time placed on the scale platen, so that sudden apparent weight spikes sensed by the load cells but attributable to events involved in patient care may be discarded as artifact, while gradual weight changes reflective of infant physiology are accumulated by the scale controller and used to provide a current weight for the infant.

摘要： A sensor output processing device has an amplifier circuit for amplifying a sensor output signal of a sensor and a buffer circuit for limiting the amplified signal to a high limit level lower than a high side voltage of a power source or a low limit level higher than a low side voltage of the power source. This limited signal is normally produced as an output signal to an external circuit. When a self-diagnosis circuit determines an abnormality in the sensor or in the amplifier circuit and the buffer circuit, the output signal is fixed to a level higher than the high limit level or lower than the low limit level.

摘要： A weighing sensor including a base (1) fixed to a housing, a load sensor (2) connected to the base in a displaceable manner via two arms (3, 4), a lever system (8 . . . 11) having at least one lever and transmitting the load acting on the load sensor to a transducer (12, 13), and a built-in calibration weight (40) which may be lowered onto a support region (30/38) for checking and/or calibrating the sensitivity of the weighing sensor. The support region is guided in a parallel manner by two additional arms (21, 22) and is connected to a lever (9/39) of the lever system (8 . . . 11) via a coupling element (26). Relatively large loads on the weighing sensor may be simulated with relatively small calibration weights, without the need for complicated lifting devices. The two additional arms (21, 22) are connected on the one hand to the support region (30/38) and on the other hand to the load sensor (2) and are located on the side of the load sensor (2) opposite from the lever system (8 . . . 11).

摘要： A measurement apparatus and a method for measuring a seat mat for a vehicle seat which serve to perform a function test or a recording of readings by way of a negative pressure that is generated in the seat mat. The negative pressure is established by way of a pressure difference between the negative pressure and the external atmospheric pressure. The method is thus independent of the external atmospheric pressure. The controller that establishes the pressure difference is embodied either electronically or mechanically.

The weighing circuit includes a zero-reset circuit for resetting the measurement to zero prior to a weighing operation. The body includes a zero-reset member incorporating an electrical switch operable by the zero-reset member to trigger the zero-reset circuit. The zero-reset member engages the surface, when the body is placed on the surface, for operating the switch to trigger the zero-reset circuit.

摘要： The present weight scale performs automated self calibration by periodically initiating a measurement operation to determine the zero offset from a true weight reading due the weight scale's intrinsic weight. The weight scale's intrinsic weight will vary due to changes in environmental conditions such as temperature and humidity, which impact the behavior of the internal electronics that perform the weight measurement operations. The automated self calibration is provided by a counter circuit, clocked by a low power oscillator, that periodically initiates the weight scale's electronics to undertake a weight measurement of the tare weight value of the scale. The tare weight value is stored in memory until replaced by a subsequent tare weight value calculation. During a weight measurement operation the gross weight measurement is deducted by the tare weight value stored in memory to arrive at a net weight representing a user's true weight.

摘要： A measuring pick-up or detector shall be made less sensitive against off-center load applications if necessary. At least it must be made certain that the off-center load sensitivity is within a permissible tolerance range. For this purpose the sensor body (1A, 1', SB) of the detector (1) to which there is applied at least one pick-up element or strain gage (5), is held for each load application in a different fixed position in a mounting (2) in such a way that, spaced from the clamping position a test load can be applied in a direction deviating from the direction and/or position of the axis of symmetry (CA, AS) of the sensor body (1A, 1', SB). A respective output signal is measured and correlated to the applied test load. At least one additional test load of the same size is applied in a different load application direction, and the respective output signal is again measured and correlated to the second test load. Then, the output signals are evaluated with reference to a tolerance range (TR) stored in a memory of a control unit (11) to determine whether a tuning of the sensor body is necessary to make the pick-up less sensitive. If such tuning is necessary, at least one tuning is performed. The tuning may be a mechanical material removal from the sensor body and/or as an electrical tuning by resistor adjustments.
