| 20110258358 | Device and Method for the Automated Detection of an Interface - In a device and a method for the automated detection of an interface between a position-measuring device and sequential electronics that are interconnected via a data-transmission channel, the position-measuring device includes an interface unit and a position-measuring unit. The interface unit is connected first of all to the data-transmission channel, and secondly to the position-measuring unit for the purpose of an internal data exchange. The interface to the sequential electronics is selectable in the interface unit from at least two interfaces. Also disposed in the position-measuring device is an interface-detection unit, which is supplied with at least one input signal that arrives from the sequential electronics via the data-transmission channel, and which includes a device for determining the time sequence of signal edges of the at least one input signal in conjunction with the signal status, as well as an evaluation unit in which the interface used to the sequential electronics is detectable by evaluating the time sequence determined, and is selectable in the interface unit. | 10-20-2011 |
| 20110218761 | ABSOLUTE POSITION MEASURING DEVICE - An absolute angle coding that includes a first cyclically continued code sequence that cyclically continues a first code sequence a multiple number of times, wherein the first code sequence is disposed within 360° and includes a first succession of code elements that defines a first angle sector. The code further includes a second cyclically continued code sequence that cyclically continues a second code sequence a multiple number of times, wherein the second code sequence is disposed within 360° and includes a second succession of code elements that defines a second angle sector, wherein the first cyclically continued sequence and the second cyclically continued code sequence in combination unambiguously absolutely encode the 360°. The first angle sector is not equal to the second angle sector, and at least one of the second code sequences of the second cyclically continued code sequence is embodied only partially within said 360° and with a succeeding second code sequence forms a joint. | 09-08-2011 |
| 20110213586 | Device and Method for Transmitting Data Between a Position-Measuring Device and Sequential Electronics - In a device and a method for transmitting data between a position-measuring device and sequential electronics via a data-transmission channel, the position-measuring device includes an interface unit and a processing unit, the interface unit being connected first of all to the data-transmission channel, and secondly, to the processing unit for the purpose of an internal data exchange with the aid of a request channel and a response channel. The interface unit includes a command interpreter by which, using conversion rules, commands which arrive via the data-transmission channel are convertible into internal requests and are able to be fed via the request channel to the processing unit, and response data which arrives from the processing unit via the response channel is convertible into output data. The interface unit further includes a rules memory for storing the conversion rules, which is at least partially modifiable. | 09-01-2011 |
| 20110209352 | LENGTH MEASURING DEVICE - A length measuring device for measuring a relative position of two objects, the length measuring device including a scale in a housing and a scanning unit displaceable in a measuring direction X relative to the scale and the housing, wherein the scanning unit is disposed inside the housing and including a heat-generating electrical component. The length measuring device further including a thermal conduction path designed for transferring heat generated at the heat-generating electrical component to the housing. | 09-01-2011 |
| 20110209351 | ARRANGEMENT AND METHOD FOR GENERATING A REFERENCE IMPULSE FOR A POSITION MEASURING DEVICE - An arrangement for generating a reference impulse for a position measuring device, wherein the position measuring device includes a scale with at least one incremental track and at least one reference mark and a scanning unit for generating position signals by scanning the at least one incremental track and for generating an analog reference impulse by scanning the at least one reference mark. The arrangement includes a reference impulse memory unit that receives the analog reference impulse and stores the received analog reference impulse as a stored reference impulse. The arrangement further includes a reference impulse generating unit in communication with said reference impulse memory unit and said reference impulse generating unit receives the stored reference impulse and at least one of the position signals, wherein the reference impulse generating unit turns on a reference impulse as a function of the stored reference impulse and an occurrence of a set condition and turns off the reference impulse if a reset condition occurs, and the set and reset conditions are derivable from said at least one of the position signals. | 09-01-2011 |
| 20110208475 | ABSOLUTE ANGLE CODING AND ANGLE MEASURING DEVICE - An absolute angle coding that includes a first code sequence disposed within 360°, wherein the first code sequence has a first length and is disposed N | 08-25-2011 |
| 20110024920 | COMPONENT ARRANGEMENT AND METHOD FOR PRODUCING A COMPONENT ARRANGEMENT - A component assembly including a carrier element including a first contact face and a semiconductor component disposed on the carrier element, wherein the semiconductor component includes a second contact face. The component assembly further includes a contact-making bonding wire, wherein one end of the contact-making bonding wire is connected to the first contact face and a second end of the contact-making bonding wire is connected to the second contact face. The component assembly includes a flow stop bonding wire positioned on the second contact face, wherein the flow stop bonding wire defines on the second contact face a first zone and a second zone. An encapsulation material is applied from the first zone to the first contact face so as to define an encapsulation for the flow stop bonding wire, wherein the flow stop bonding wire prevents an uncontrolled flow of the encapsulation material into the second zone. | 02-03-2011 |
