20090273386 | APPARATUS FOR CURRENT-TO-VOLTAGE INTEGRATION FOR CURRENT-TO-DIGITAL CONVERTER - Methods and apparatus for improved current-to-voltage integrators reducing charge injection and kT/C errors from capacitor switching and intrinsic operational amplifier noise (i.e., offset, 1/f noise, thermal noise) during the reset cycle of the integrator, simultaneously reducing demands on the reference voltage source, using correlated double sampling to compensate for DC offset and low frequency op-amp noises, and “fake” integration and a capacitor divider to eliminate or significantly reduce kT/C noise and charge injection. | 11-05-2009 |
20090273392 | METHODS AND APPARATUS FOR REDUCING NON-IDEAL EFFECTS IN CORRELATED DOUBLE SAMPLING COMPENSATED CIRCUITS - Embodiments of the present invention address kT/C noise, sampled high frequency operational amplifier noise, and charge injection errors sampled on switching capacitors and introduced due to internal switching. Correlated double sampling compensates for DC offset and low frequency operational amplifier noise, and the use of fake integration and a capacitor divider eliminate or significantly reduce kT/C noise, sampled high frequency operational amplifier noise, and charge injection errors. | 11-05-2009 |

20110115612 | MEDIA MANAGEMENT SYSTEM FOR SELECTIVELY ASSOCIATING MEDIA WITH DEVICES DETECTED BY AN RFID - A system and method for managing media is described herein. The system includes a camera oriented towards a visually distinguishing mark, at least one actuation device that generates an instruction for at least one of the camera and an RFID reading system, and a central control unit in communication with the camera and the RFID reading system. In response to an instruction from the at least one actuation device, the RFID reading system detects an RFID device neighboring the visually distinguishing mark and transmits a first identifying information of the detected RFID device to the central control unit. The central control unit receives an image captured by the camera, creates a media file including the captured image and the received first identifying information, and transmits the media file to a server. | 05-19-2011 |
20110115930 | IMAGE MANAGEMENT SYSTEM AND METHOD OF SELECTING AT LEAST ONE OF A PLURALITY OF CAMERAS - A media management system and method of selecting at least one of a plurality of cameras is described. The system includes a plurality of image-taking systems, each one including a camera having a plurality of control functions; and a camera control unit for controlling operation of the camera. The control unit includes a communication unit for communicating with the plurality of image-taking systems and a mobile communication device, the communication unit establishing an image capturing session with the mobile communication device in response to an initiation by the mobile communication device; and a processor that uses a location of the mobile communication device to select at least one image-taking system from the plurality of image-taking systems. The control unit transfers at least one of the plurality of control functions to the mobile communication device, and the mobile communication device operates the camera to capture at least one image. | 05-19-2011 |
20110115931 | IMAGE MANAGEMENT SYSTEM AND METHOD OF CONTROLLING AN IMAGE CAPTURING DEVICE USING A MOBILE COMMUNICATION DEVICE - An image management system and method of controlling an camera using a mobile computing device is described. The system includes a mobile computing device and an image taking system connected to a server. The image taking system includes a camera oriented towards distinguishing mark; and a control unit in communication with the mobile computing device such that the control unit transfers the control functions of the camera to the mobile computing device such that the mobile computing devices operates the camera to capture an image. The method includes establishing, by a mobile communication unit, an image capturing session with an image capturing system, the image capturing system having a control unit; transmitting, by the control unit, to the mobile computing device control functions for controlling operation of a camera; capturing, by the camera, an image in response to operation by the mobile communication unit; and creating, by the image capturing system, a media file. | 05-19-2011 |
20130099893 | LOCK CONTROL SYSTEM USING RFID - A lock control system includes a detection unit positioned proximate to a lock, an RFID device neighboring at least one RFID antenna, and an RFID reading system detecting identifying information of the RFID device when the detection unit detects an event. The system also includes at least one microcontroller that determines, based on the identifying information, whether to grant the RFID device access to an area secured by the lock and instructs an actuator to unlock the lock when the RFID device is granted access. | 04-25-2013 |
20130099927 | ASSETS AND PERSONNEL TRACKING USING RADIO FREQUENCY IDENTIFICATION - A system for updating a location of a target with an RFID device in response to detected motion of the target includes a server and tracking modules. The server stores identifying information for RFID devices and locations associated with the devices. The tracking modules are positioned in predetermined locations and communicate with the server. Each tracking module includes a motion processing module and an RFID reader. In response to motion detected by a motion processing module, the RFID reader detects identifying information for an RFID device neighboring an RFID reader and transmits the information to the server. | 04-25-2013 |
