摘要:
The invention is directed to a method for determining a temperature by means of a radiation thermometer with multiple infrared sensor elements detecting infrared radiation from different regions and delivering corresponding temperature signals, in particular to a method for taking a patient's temperature by means of an ear thermometer. The method of the present invention is based on the known fact that the tympanic membrane has a higher temperature than the ear canal. Hence part of the sensor elements, that is, those that view the tympanic membrane, will detect a higher temperature than the remaining sensor elements that view the ear canal. According to the present invention, for evaluation only the temperature signal of that sensor element is used that supplies the peak temperature value by comparison with the other sensor elements.

The invention is directed to an infrared thermometer with a heatable probe head, in particular a clinical thermometer for taking a patient's temperature in the ear, and to a heatable protective cover. The probe head possesses a radiation inlet zone at its forward end. A heating element is also arranged there. The heating element is either connected to a protective cover adapted to be fitted over the probe head or secured to the forward end of the probe head.

The invention is directed to a thermopile sensor and in particular to a radiation thermometer or a motion detector with a thermopile sensor. The thermopile sensor includes a thermopile supported in a housing. The thermal capacity of the cold and hot junctions of the thermopile including its supporting structure and the thermal conductivity of the supporting structure are mutually coordinated such that a change in the housing's temperature produces a change of equal magnitude in the cold and hot junctions' temperature, that is, no temperature gradients occur within the thermopile.

The invention is directed to an infrared thermometer and a temperature calculation method suitable for determining the body temperature at different measurement sites, for example, on a person's forehead or in the ear. The thermometer includes a device for attaching a demountable probe head. Provision is made for different probe heads that are adapted to fit the different measurement sites.

The invention is directed to a method of computing the radiation temperature of a body from the signals of a radiation and an ambient temperature sensor, and further to a radiation thermometer, in particular a clinical radiation thermometer. In the method of the present invention, computation of the temperature is not using the Stefan Boltzmann law, but rather, a polynomial is used, preferably a third-degree polynomial, which is adjusted to the radiation-optical properties of the thermometer in the relevant wavelength range. The reciprocal value of the sensitivity of the radiation sensor is preferably represented as a polynomial as well. In this manner, the computation of a fourth root or divisions which are otherwise customary are avoided, enabling the necessary computations to be also performed, for example, by a 4-bit microprocessor with great speed.

A toothbrush drive includes a first drive component for generating a magnetic field and a second drive component driven in both a translational and rotational manner under the influence of the magnetic field. A transmission element is deflected out of a predetermined position for transmission of both translational and rotary movement of the second drive component. The deflection of the transmission element varies along its longitudinal axis. A transmission element can be deflected out of a predefined position for transmission of a translatory movement and a rotational movement of the second drive component to the brush element along a longitudinal axis of the transmission element. The deflection of the transmission element out of the predefined position is varied along the longitudinal axis of the transmission element.
摘要:
The present invention is concerned with an epilator that comprises a housing, an epilation cylinder mounted at a head region of the housing for plucking hairs from the skin during operation, and an attachment detachably connected with the housing, which attachment comprises at least a shaving blade defining a use direction along which the shaving blade is to be drawn over the skin to shave off hairs. In the attached state the shaving blade is disposed behind the epilation cylinder with respect to the use direction so that during operation the epilation cylinder plucks hairs from the skin and the shaving blade contacts the skin to shave off hairs from the skin in successive order during a single stroke of the epilator over a skin area, wherein the attachment is connected with the housing in the head region such that the epilation cylinder is partially covered by the attachment and a non-covered part of the epilation cylinder extends into an aperture of the attachment.
摘要:
An epilation device is proposed that has a housing, a roll-like epilation implement mounted at the housing, which epilation implement has clamping units for successively clamping and plucking hairs, and the epilation device has further a powered motor operatively coupled to the epilation implement, and a motor control. The proposed epilation device is arranged to have at least a fast operation mode in which the motor is controlled by the motor control such that the clamping units move with a circumferential speed of more than 2.5 meters per second relative to the housing. This serves to e.g. achieve a gap-less clamping and plucking in a use direction (U) even if the epilation device is drawn over the skin with a relatively high speed.

An epilator (100) comprising an epilating unit (1) for plucking and/or pulling hair (51) out of the skin (50) over an epilating width (E). Such an epilator is disadvantageous in that typically not all of the hairs are detected by the epilating unit (1) and some remain in the skin after the epilation. A subsequent epilation would then be required. In order to solve this problem, the epilator (100) has a hair removal unit (2) following the epilating unit (1) in the direction (B) of use, such that, in at least one operating mode, the hair removal unit (2) removes the hairs (51) that have not been pulled out by the epilating unit (1)
摘要:
An electric shaving apparatus including a housing and a shaving head. The shaving head is coupled to the housing by at least one first elastic element and includes at least one first shaving element. The electric shaving apparatus includes in addition an electric motor for generating an oscillatory motion of the shaving head and an oscillatory motion differing therefrom of at least one second shaving element. The electric motor includes two drive components of which a first drive component is adapted to be driven to oscillate relative to a second drive component. One of the drive components is connected to the second shaving element. The second shaving element or a drive part connected thereto is equipped with an elastic connection to the shaving head.
