  • Patent number: 9286741
    Abstract: A method and apparatus for controlling access from a first area to a second area includes receiving an identity signal from an identifier input device, and checking for stored data indicating that the identity represented by the identity signal is registered as present in the first area. If a predetermined access requirement is fulfilled, then a pass signal at the first access controller is generated. To control access from the second area to a third area, an enter message is sent to a second controller with at least the identity and data indicating that the identity is present in an access area of the second controller. An exit message is sent to a third controller controlling access to the first area, including at least the identity and data indicating that the identity is not present in an access area of the third controller.

  • Patent number: 9070021
    Abstract: A method and a system is provided for monitoring an area by a monitoring camera (1). A protected zone (5) is defined within the monitored area (2) and a suspicious object (9a, 9b) is detected as an object present both inside and outside the protected zone. A key position of the suspicious object is determined, and it is determined if the key position is inside or outside the protected zone (5). If the key position is outside the protected zone a first action is triggered.

  • Patent number: 9007474
    Abstract: A pan-tilt camera is arranged to include a camera head, a stationary unit, an intermediate member arranged between the camera head and the stationary unit, a first rotary joint rotatably connecting the camera head to the intermediate member, and a second rotary joint, rotatably connecting the intermediate member to the stationary unit. A communication path is provided between the camera head and the stationary unit, including an optical waveguide arranged between the camera head and the stationary unit. The optical waveguide has a first end positioned at the first rotary joint to receive light from the camera head through the first rotary joint. The other end of the waveguide is positioned at the second rotary joint and is arranged to send light to the stationary unit through the second rotary joint.

  • Patent number: 8209414
    Abstract: A method for connecting a storage device to an information generating device includes transferring an identifying message from the storage device to a control server via a computer network. The identifying message includes a unique identifier uniquely identifying the storage device, matching a registered information generating system to the unique identifier, and identifying at least one information generating device included in the matched information generating system. A configuration message is transferred from the control server to the storage device, and the configuration message includes an address to the identified at least one information generating device and instructions of interaction. The instructions of interaction are arranged to define how the transfer of generated information is to be performed.

  • Patent number: 7256834
    Abstract: A digital camera (300) has panning and/or tilting functionality and comprises: a camera housing (6) with an optical input (400), such as a lens or objective (8); an image capturing unit (500) for producing a digital image from light received through the optical input; and a controller (600). A first mirror (9) is mounted externally to the camera housing (6). An image rotating device (200) receives an angular displacement control signal from the controller (600) and rotates the first mirror at an angle with respect to the optical input (400, 8) of the camera housing (6).

  • Patent number: 6920319
    Abstract: A method and apparatus is disclosed for providing a range of location dependent information and services to users of wireless devices coupled to the multi-point wireless access network of the current invention. In an embodiment of the invention a multi-point wireless access network for servicing wireless devices is provided. The multi-point wireless access network includes: wireless access devices, an inventory map and a server. The wireless access points are arrayed in a coordinate system with a known relative relationship to one another. Each of the wireless access points provides communication capabilities for corresponding proximate ones of the wireless devices. The inventory map correlates selected ones of the wireless access points with corresponding inventory located proximate to each of the selected ones of the wireless access points.

  • Publication number: 20030220116
    Abstract: Method and Apparatus are disclosed for determining the position of a portable device in a wireless network formed by a plurality of base stations. In an embodiment an apparatus for determining a location of a wireless device in a wireless communication network provided by a plurality of base stations is disclosed. The apparatus comprises a signal strength table and a positioning service module. The signal strength table characterizes signal strengths relative to each of plurality base stations at each of a plurality of locations in the wireless communication network. The positioning service module correlates an actual received signal strength for a communication with the wireless device with at least one of the received signal strengths in the signal strength table, to determine the position of the wireless device. Alternate means and methods are also disclosed for determining the position of the portable device.
