The climate cabinet includes an object storage device, a first intake and output station for the intake and output of objects and an associated first transport device for positioning objects in the object storage device, and has a second intake and output station for the intake and output of objects and an associated second transport device for positioning objects in the object storage device. A system is also provided. The system includes the climate cabinet and multiple workstations, which can each be situated adjacent to the intake and output stations of the climate cabinet, so that the transport devices of the climate cabinet, which are associated with the intake and output stations, can serve the workstations.

In a method for adjusting the temperature of a motor vehicle seat, which includes a seat ventilating system and a seat heater, to a predetermined desired value, in which the temperature of the seat is detected in the region of a seat surface by a first temperature sensor and the outside temperature is detected by a second temperature sensor, the seat ventilating system is switched off below a first temperature threshold for the outside temperature, and the seat heater is switched off above a second temperature threshold for the outside temperature. By these measures, an occupant may be provided with a comfortable micro-climate in the seat region for his/her well-being.

A motor vehicle seat has a base element which can be fastened in the motor vehicle, a seat element which is disposed on the base element, and a backrest element which is disposed on the seat element. The seat can be adjusted between a locked position and an unlocked position. In the locked position, the seat element and the backrest element can be used for normal sitting. In the unlocked position, the seat element and/or the backrest element are adjusted in the vehicle to the front with respect to the driving direction far enough so that a space arranged behind the seat with respect to the driving direction is accessible for loading and unloading. For adjustment between the locked position and the unlocked position, the seat element is swivellably disposed on the base element and/or the backrest element is swivellably disposed on the seat element. In order to reduce stress on the seat during a restoring movement from the unlocked position to the locked position, damper devices are provided in order to counteract the restoring movement at least during its end phase.

An electrochemical sensor is provided containing a supporting material having a surface of noble metal such as gold or palladium to which is bound an enzyme such as glucose oxidase via binding molecules. The binding molecules are in the form of a homogenous monolayer and are bound to the metal surface by anchor groups such as thiol, disulphide or phosphine groups. The enzyme is linked to the binding molecules by an ionic bond, a covalent bond or a metal-chelate bond. The binding molecules may contain a spacer such as an alkylene chain. Coverage of the binding molecules on the metal surface is less than the maximum coverage to optimize enzyme coverage, decrease response time of the sensor and increase signal yield per surface area. The monolayer may contain diluent molecules which are not linked to an enzyme and which are bound to the metal surface via anchor groups. The diluent molecules lower the concentration of binding molecules in the monolayer, increase conductivity of the monolayer and lower unspecific binding of components from a sample solution in contact with the sensor. The binding molecules can be linked by an ionic bond or a metal-chelate bond, respectively, to a charged amino acid residue or a chelate-forming amino acid residue of the N-terminus, C-terminus, or N- and C-terminus of recombinant enzyme protein.
摘要:
In a passive infrared movement detector having a reflector which directs the radiation from a plurality of fields of vision to an infrared detector arrangement and for this purpose consists of a plurality of individual reflectors, the reflecting surface of the reflector is composed of a plurality of facets produced at the reflector. The disadvantages of such a reflector are in particular to be seen in the fact that for each required distance range of the passive infrared movement detector a reflector adapted thereto must be used. Furthermore, the production of such a reflector is relatively expensive. In order to avoid these disadvantages, the individual reflectors are proposed to be in the form of spherical reflectors which are arranged on a reflector carrier in a manner so as to be shiftable in different directions and lockable in adjusted positions.

A packaging film which contains pigment particles randomly distributed in a low surface-area density is used for the authentication of products. An imaging device is used to record a first digital image of a packaged product. The positional coordinates, and optionally the color values, of the pigment particles contained in the packaging film are determined from the digital image by means of a computer program and an identification code is calculated from the coordinate or color values and stored in a database. To authenticate the product at a later time, a second digital image is recorded and a test code is determined and compared with the recorded identification code.

A process is described for preparing aromatic diazonium salts, wherein the starting compound is an aromatic amide and the amide bond is first split hydrolytically and the amine compound thus obtained is diazotized with an inorganic nitrite salt. The diazonium salts thus obtained can be converted to stable salts and then serve as starting materials for further reactions, such as the Heck reaction.

A vehicle seat has a seat frame which is arranged in a vertically adjustable manner above a seat underframe. A backrest part is mounted on the seat frame, and a seat cushion carrying part, for adjusting the seat cushion depth, is displaceably disposed by an end area in two guides. The other end area of the seat cushion carrying part is supported by two additional guides. The additional guides are supported by way of a supporting construction past the seat frame directly on the seat underframe.

A support crucible includes a central axis, outer radii including longest outer radii defining planes with the central axis, a side wall region having a circumferential direction and a bottom. At least two neighboring segments are separated by joints extending substantially vertically in the side wall region to the bottom and penetrating the bottom. The joints define opposed surfaces of the neighboring segments which always overlap each other in the circumferential direction of the side wall region in an operating state. Each of the surfaces is intersected by a respective one of the planes, at least in the side wall region. According to another embodiment, the joints defining opposed surfaces of the neighboring segments have complementary shapes, the surfaces are formed by cuts beginning at a jacket surface of the side wall region and extending parallel to the central axis and at an angle to the planes, and the cuts extend in a curve to the central axis. A method for producing such a support crucible includes producing the crucible segments by beginning cuts at starting points on the jacket surface to be cut apart into the segments, and directing each of the cuts parallel to the central axis at an angle to one of the planes at one of the starting points and in a curve beginning at one of the starting points and extending to the central axis.
