Publication number: 20240004992Abstract: In an embodiment an integrated circuit comprises a plurality of ports. Of a plurality of gating circuits, each gating circuit blocks or grants access to at least one of the ports depending on a release signal. From a plurality of configuration registers, each configuration register for stores the information to which group a gating circuit of the plurality of gating circuits belongs. A tag evaluation circuit receives an identifier from an access request from a component and outputs a group identifier for the access. There is a plurality of comparison circuits. Each comparison circuit compares the group identifier with the content of one of the configuration registers and outputs the release signal to a gating circuit of the plurality of gating circuits.Type: ApplicationFiled: June 30, 2023Publication date: January 4, 2024Inventors: Patrik Eder, Rainer Wolfgang Kaiser

Patent number: 9885687Abstract: Arrangements are described for evaluating characteristics of target molecules. A biochip is received which includes a substrate to which charged probe molecules are attached. The probe molecules have a marker to allow generating signals indicative of the distance of a portion of the probe molecule from the substrate. The signals are detected and means for an external electric field is generated to which the probe molecules are exposed. A control means acts to: (A) apply an external electric field causing the portion of the probe molecule to approach the substrate, and (B) apply an external electric field causing the portion of the probe molecule to move away from the substrate. The signal is recorded as a function of time during step (A) and/or step (B). Steps (A) and (B) are repeated for a predetermined number of times and the recorded signals are combined.Type: GrantFiled: September 17, 2015Date of Patent: February 6, 2018Assignee: Dynamic Biosensors GmbHInventors: Ulrich Rant, Wolfgang Kaiser, Paul Andreas Hampel, Jens Niemax, Andreas Langer, Jelena Knezevic

Patent number: 9830761Abstract: An electronic key having the following features. The electronic key has a key housing and a switch housing in the key housing. The switch housing has an inherently rigid frame having at least one first breakout, and a flexibly deformable membrane which is arranged on the frame in order to close the at least one breakout and to forward a force having effect from the outside on the membrane in the region of the breakout to an electrical switch element arranged within the frame. An electronic key having the required amount of stiffness is thus created, in which sensitive electronic components located therein are also protected from environmental influences. If the deformable membrane is not only used for button-related functions, but also for forming an ejection section for an emergency key or as a rattle protection for the emergency key, a multifunctional switch housing can thus be created simply.Type: GrantFiled: March 19, 2014Date of Patent: November 28, 2017Assignee: Continental Automotive GmbHInventors: Wolfgang Kaiser, Rudolf Renner, Florian Schweiger

Patent number: 9570254Abstract: A portable electronic user device, in the form of an electronic key, having an inherently rigid button for activation by a user. The portable electronic user device further has a flexibly deformable membrane including a first side having at least one support section on which the at least one button is supported via the plunger, and an actuating section, separate from the at least one support section, for receiving and forwarding an actuation of the button to an electrical switch element. There is a rigid frame which bears the membrane on a second side opposite the first side, wherein, in the assembled state, having the membrane in the region of the at least one support section, the frame has at least one breakout, via which the membrane is moveable by the plunger upon activating the at least one button and, in dependence on the size and/or the shape of the breakout, provides a force for resetting the button.Type: GrantFiled: March 19, 2014Date of Patent: February 14, 2017Assignee: Continental Automotive GmbHInventors: Thomas Kropf, Wolfgang Kaiser, Florian Schweiger, Rudolf Renner

VCSEL with non-circular mesa and current confinement aperture for higher order lateral mode emission
Patent number: 8355423Abstract: A vertical cavity surface emitting laser (VCSEL) (100) has a substrate (104), on which are disposed first and second distributed Bragg reflectors (DBRs) (106, 112), each DBR comprising a stack of layers of alternating refractive index, an active layer (108) disposed between the DBRs, and an aperture layer (110) disposed either between the DBRs or within one of the DBRs. The aperture layer (110) has a border (116) having an internal boundary with a plurality of indented portions defining one or more apertures. Such a VCSEL is easily manufacturable and provides a narrow bandwidth output, as well as mitigating at least some of the problems of prior art VCSELs. Mesa (102) may be etched to be non-circular and subsequent selective oxidation of aperture layer (110) results in a non-circular current confinement aperture (114) promoting higher-order lateral modes (LP21).Type: GrantFiled: September 30, 2009Date of Patent: January 15, 2013Assignee: Oclaro Technology LimitedInventors: Michael Moser, Sven Eitel, Wolfgang Kaiser -
