Abstract: A stand, for example, for mounting a medical instrument, has a first part and second part which is connected to the first part in a rotationally movable manner via a rotary joint and can be moved relative to the first part about an axis of rotation. The stand includes a drive module supported on the first part. The module having a drive member coupled to the second part. A control device having a controller is connected to the drive module and intended for setting a drive torque provided by the drive member. The control device includes a torque sensor for detecting a torque acting on the second part and a control-signal assembly connected to the controller. The control-signal assembly from the torque detected and a setpoint value generates a signal, which is fed to the controller and is intended for setting the drive moment provided by the drive member.

Abstract: The present disclosures relates to a head-wearable hearing device comprising an ambient microphone arrangement configured to receive and convert environmental sound into a microphone input signal and an ear canal microphone configured to receive and convert ear canal sound pressure into an electronic ear canal signal. The head-wearable hearing device further comprises a mixer combining a compensated ear canal signal and the microphone input signal to produce a hybrid microphone signal. The hybrid microphone signal may be transmitted to a far end recipient through a wireless or wired data communication link.

Abstract: A hearing device includes: at least one microphone for converting sound received by the at least one microphone into an audio signal; a sound impulse detector configured for detecting a presence of an impulse in the audio signal; and a signal processor configured for processing the audio signal into a processed audio signal in response to the presence of the impulse in the audio signal as detected by the sound impulse detector; and a receiver coupled to the signal processor for converting the processed audio signal into an output sound signal for emission towards an eardrum of a user; wherein the sound impulse detector is configured for operation in a frequency domain for detecting presence of the impulse in the audio signal.

Abstract: The invention relates to a medical apparatus having a medical optical appliance and a holding device with at least two holding arms which are connected movably to one another with at least one degree of freedom of movement via a joint and with an actuator which is connected to the two holding arms in such a way that a force can be exerted via the actuator between the two holding arms in the direction of the degree of freedom of movement. A control unit comprises a first regulator for outputting a first control signal to the actuator via an adjusting element. The medical optical appliance is mounted on the holding device.

Abstract: A visualization apparatus for a surgical site includes a recording unit for recording an image of an object arranged in a focal plane of the recording unit. The recording unit has a lens having an optical axis that intersects the focal plane at a point P. An electronic image representation unit has an image surface for reproducing the recorded image and point P is reproduced at image point P?. A mirror unit has a mirror surface, which has a center point S and is arranged relative to the image surface such that the reproduced image is reflected by the mirror surface. The focal plane, image surface and mirror surface are arranged relative to one another such that an observation point B results for which the following applies: ?2 D<?1??2<+2 D; wherein: ?1=?1/d1 ?2=?1/d2 d1=distance PB d2=distance P?S+distance SB.

Abstract: A computer system and method generate orders to be executed in an electronic exchange, and execute the orders. An order data processor processes order data, and an order transmitter transmits an order to the electronic exchange based thereon. The order data includes at least one price limit which specifies a range of prices that is required for the order to be executed. The order is executable within the price range only. If the order is a buy order, the at least one price limit includes a minimum price to execute the buy order, and if the order is a sell order, the at least one price limit includes a maximum price to execute the sell order. The order is added to an order book for being executed at the end of a call auction. A derivatives trader may thus reduce the risk of having incorrect inventory in an underlier.

Abstract: The invention concerns a device for carrying out the minimally invasive withdrawal of blood from animals by using blood-sucking assassin bugs. Blood samples are required within the scope of many testing arrangements, hence blood withdrawals are one of the most common interventions. In all known methods, a tapping of a blood-stream is carried out using a medical instrument. These blood withdrawals are often complicated and are subject to strict regulations. Furthermore, the animals have to be anesthetized sometimes. Assassin bugs have also been used for withdrawing small quantities of blood. The blood of bats stored in the abdomen of the assassin bugs is removed for tests. However, it is often difficult to locate the bug after it has sucked blood because it quickly flees to dark places. The inventive device is comprised of at least one receptacle (1), which has at least one perforated outer wall (1.
