  • Patent number: 8973731
    Abstract: An exemplary device for controlling power associated with a passenger conveyor motor includes a regenerative drive that is configured to facilitate providing electricity generated by the motor to a power source when the passenger conveyor is moving. The controller determines when an operating condition of the regenerative drive is outside of a desired range and responsively prevents the regenerative drive from facilitating providing the electricity to the power source.

  • Patent number: 8976843
    Abstract: In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

  • Patent number: 8974856
    Abstract: The present invention provides a method for fabricating a ceramic film on a copper foil. The method comprises applying a layer of a sol-gel composition onto a copper foil. The sol-gel composition comprises a precursor of a ceramic material suspended in 2-methoxyethanol. The layer of sol-gel is then dried at a temperature up to about 250° C. The dried layer is then pyrolyzed at a temperature in the range of about 300 to about 450° C. to form a ceramic film from the ceramic precursor. The ceramic film is then crystallized at a temperature in the range of about 600 to about 750° C. The drying, pyrolyzing and crystallizing are performed under a flowing stream of an inert gas. In some embodiments an additional layer of the sol-gel composition is applied onto the ceramic film and the drying, pyrolyzing and crystallizing steps are repeated for the additional layer to build up a thicker ceramic layer on the copper foil. The process can be repeated one or more times if desired.

  • Publication number: 20150063786
    Abstract: A method for tracking an object in a plurality of frames includes obtaining a contour of an object in a frame. For each remaining frame among the plurality of frames, the following steps are performed. A probability map generator generates a plurality of probability maps containing probability values for one or more pixels for a current frame. A contour is estimated for the current frame based on the plurality of probability maps. User input is obtained for refining the estimated contour. Based on the user input, one or more local regions to be added and/or removed are identified and recorded in a local region list. The local region list is maintained and updated during the tracking process and is used together with the probability map generator.

  • Publication number: 20150065006
    Abstract: A toy gun in the form of a breech loading rifle is provided which is capable of firing a projectile such as a dart as well as simultaneously or near simultaneously emitting smoke from the muzzle of a barrel of the gun after the dart has been discharged from the muzzle. The toy gun has first and second rechargeable air pumps. A first one of the air pumps automatically discharges stored air into a breech part of the barrel in order to propel a loaded projectile from the gun's barrel. A second one of the air pumps expels stored air through a flow restriction device which doubles up as a pressure switch for actuating a smoke generator located adjacent to the muzzle of the gun. The second air pump also provides a low flow rate of air through the smoke generator to expel smoke from the smoke generator. The second air pump expels stored air much more slowly than the first air pump. The first and second air pumps are simultaneously triggered to release stored air by user actuation of a trigger of the gun.

  • Publication number: 20150063178
    Abstract: Systems and methods are provided for avoiding in-device coexistence interference on a user equipment. A first wireless communication circuitry and a second wireless communication circuitry operate concurrently on the user equipment. The second wireless communication circuitry detects an operational status of the first wireless communication circuitry, and determines if the operational status is transmission or reception. In response to determining that the operational status is transmission, the second wireless communication circuitry avoids receiving data. In response to determining that the operational status is reception, the second wireless communication circuitry avoids transmitting data.

  • Publication number: 20150063344
    Abstract: Embodiments of the present invention disclose a data boundary determining method, an indication information sending method, and apparatuses thereof. The boundary determining method includes: acquiring, by a base station in which a non-reference cell locates, timing information of a reference cell, or a parameter used to determine boundary information of a high speed dedicated physical control channel (HS-DPCCH); and determining, by the base station, the boundary information of the HS-DPCCH according to the timing information of the reference cell or the parameter, where the boundary information is used by the base station to search for the HS-DPCCH. The present invention solves a technical problem in the prior art that a base station in which a non-reference cell locates is not capable of finding a correct boundary of the HS-DPCCH and therefore causes a decrease in downlink data transmission performance.

  • Publication number: 20150062503
    Abstract: Provided is a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition may form a pressure-sensitive adhesive having a fine phase separation structure by a block copolymer including a hard segment and a soft segment, and also has a high elastic modulus and an excellent pressure-sensitive adhesive property. For example, although applied to a thin polarizing plate on at least one surface of which a polarizer protective film is not used, the pressure-sensitive adhesive may allow the polarizing plate to exhibit excellent durability, moisture resistance, workability, a pressure-sensitive adhesive property and a light leakage inhibiting ability.

  • Publication number: 20150066498
    Abstract: A low power sound recognition sensor is configured to receive an analog signal that may contain a signature sound. The received analog signal is evaluated using a detection portion of the analog section to determine when background noise on the analog signal is exceeded. A feature extraction portion of the analog section is triggered to extract sparse sound parameter information from the analog signal when the background noise is exceeded. An initial truncated portion of the sound parameter information is compared to a truncated sound parameter database stored locally with the sound recognition sensor to detect when there is a likelihood that the expected sound is being received in the analog signal. A trigger signal is generated to trigger classification logic when the likelihood that the expected sound is being received exceeds a threshold value.

  • Publication number: 20150066495
    Abstract: A low power sound recognition sensor is configured to receive an analog signal that may contain a signature sound. Sparse sound parameter information is extracted from the analog signal and compared to a sound parameter reference stored locally with the sound recognition sensor to detect when the signature sound is received in the analog signal. A portion of the sparse sound parameter information is differential zero crossing (ZC) counts. Differential ZC rate may be determined by measuring a number of times the analog signal crosses a threshold value during each of a sequence of time frames to form a sequence of ZC counts and taking a difference between selected pairs of ZC counts to form a sequence of differential ZC counts.
