A car apron assembly is provided that includes a car apron attached to the elevator car at the elevator car door sill, a first triggering element connected to at least one landing door, and a second triggering element operably connected to the car apron. The car apron is deployable from a stowed state to a deployed state when the first triggering element engages and actuates the second triggering element.

Abstract: A method and system for testing an elevator car door interlock and deterrent mechanism in an elevator system is disclosed. The method includes the steps of: ensuring that no passengers are in the elevator car and closing the elevator car door; operating the elevator car to move it away from the selected landing; commanding the elevator car door to open for a predetermined duration and measuring the displacement of the elevator car door from a closed position; and closing the elevator car door and operating the elevator car to return to a landing.

Abstract: Methods and systems for reporting issues in an elevator system are provided. The reporting system includes a display located within an elevator car, an input device configured to receive input from a passenger within the elevator car, and a computing system having a processor and a memory, the computing system configured to generate a user interface on the display and configured to receive input from the input device, wherein the memory includes a list of possible issues related to the elevator car. The computing system is configured to generate a user report based on the received input, and transmit the user report to a remote location.

Abstract: A method for installing an elevator drive machine in a machine room-less elevator system is provided. A drive machine assembly is fastened to a counterweight. The counterweight is then lifted vertically along a set of counterweight guide rails to the top of the hoistway. There, the drive machine assembly is mounted to the ends of the counterweight guide rails. Once in place, the drive machine assembly is then disconnected from the counterweight.

Abstract: A method and system for managing at least one elevator (102) is disclosed.

Abstract: The present invention describes a system and method for controlling interactive video, including a remote control device allowing the user to interact with the video. The method allows bringing the “lean-forward” hypervideo experience to a “lay-back” environment such as the TV screen. The method also allows for the creation of a single system that combines both the social aspects of the “lay-back” and the “lean-forward experience” into a new type of rich media viewing experience.

Abstract: A viewer interaction system and method receives video data from a video source and identifies object content in the received video data. A video signal is generated that represents the video data. That video signal is communicated to a display device which displays a video image representative of the video signal. The system and method monitor user interaction with the displayed video image and selects an interactive activity based on the user's interaction with the displayed video image and the identified object content in the received video data.

Abstract: A contextual advertising system and method receives video data and multiple advertisements associated with the video data. The system and method identify object content in the received video data and generates a video signal representing the video data. The video signal is communicated to a display device which displays a video image. User interaction with the displayed video image is monitored by the system and method. An advertisement is selected from the multiple received advertisements for display to the user. The advertisement is selected based on the user interaction with the displayed video image and the identified object content in the video data.

Abstract: Proposed is a model for generation and use of metadata for interactive video navigation and video content identification.

Abstract: More and more personal or confidential information is stored in storage devices such as but not limited to, laptops, cell phones or USB keys, which are mobile per essence. Due to their mobility, such devices tend to be left unattended or even be lost, compromising the security of the data. This invention is a method to prevent access to the data on a mobile storage device when the intended recipient or user is not in closed range. The invention relies on the use of wireless communication protocol such as but not limited to RF, Bluetooth or Wi-fi to pair a security device with the storage device to enable its functionality. When the security device is not in communication range of the storage device, the data is made inaccessible. A data storage device may include a wireless communication interface used to secure the data, wherein the data storage is partitioned, with each partition having a different security profile.

Abstract: A content distribution system and method receives content from a content source and decodes the received content. The system and method identifies at least one undesired virtual channel associated with the received content and removes content associated with the undesired virtual channel. The remaining content is then consolidated into a consolidated frequency range, encoded, and distributed within a distribution environment.

Abstract: A content distribution system and method receives content from a content source and encodes the received content to generate encoded content. The encoded content is modulated to generate modulated content. A frequency is selected for distributing the modulated content. A determination is made regarding whether the selected frequency is available for distributing the modulated content. If the selected frequency is not available, alternate frequencies are selected until an available frequency is identified. If the selected frequency is available, the modulated content is then distributed using the selected frequency. Existing display devices equipped with appropriate tuners do not need any additional hardware or software to receive such content.

Abstract: A content distribution system and method receives data from a data source and identifies at least one unused channel in the received data. The unused channel is filtered and identified as an available content transmission channel. Content is then received from a content source and encoded to generate encoded content. The encoded content is modulated to generate modulated content, which is distributed within a distribution environment using the available content transmission channel.
