  • Patent number: 11956061
    Abstract: An active repeater device includes a primary sector and at least a secondary sector communicatively coupled to the primary sector receives or transmits a first beam of input RF signals having a first beam pattern from or to a base station, respectively. The primary sector includes an baseband signal processor and a first radio head (RH) unit. The secondary sector comprises a second RH unit. Beamforming coefficients are generated to convert the first beam pattern of the first beam of input RF signals to a second beam pattern based on a location of each of a plurality of user equipment (UEs). A second beam of output RF signals in the second beam pattern is transmitted from or received by, respectively, the secondary sector to or from, respectively, the plurality of UEs based on the generated beamforming coefficients and the received first beam of input RF signals.

  • Publication number: 20200391676
    Abstract: The disclosed invention relates to a removable protective device that attaches to the side of a vehicle in order to protect the vehicle from minor damage that often occurs from the inadvertent opening of adjacent vehicle doors. More specifically, the present invention is a padded protector strip having tapered ends with a gradual chamfer, wherein one end is inserted into the gap of the front driver or passenger side door hinge. The protector strip attaches magnetically to the vehicle door, while the insertion of one of the tapered ends into the gap of the door hinge prevents undesired removal from the vehicle when the door is closed. The removable protective device provides protection from incidental damage to the vehicle doors, and can be rolled up and secured in a coil configuration for easy and convenient storage.

  • Patent number: 8782081
    Abstract: A database query template and metadata mapping provide an end-user to generate customized database reports via a user interface. The parameters and data available to the end-user can be modified by editing the database query template and metadata mapping without modifications of the underlying system. A database query template includes query language keywords, variables, and template-tokens and defines the metrics, dimensions, data comparisons, filters, and aggregations available to an end-user. Template tokens include restriction tokens for comparing and filtering data, options-section-tokens for defining and omitting sections of the query template, and descriptor tokens for identifying dimensions and metrics of the database. The database query template is transformed into a database query based on values input by a user. The metadata mapping associates the variables of the database query template to the database data model and can include data constraints for validation of user input.

  • Patent number: 7824077
    Abstract: A lamp structure has a slim light emitting source including at least one LED packaged on a multilayered printed circuit board type aluminum base. A funnel-shaped reflector is concaved toward a center thereof and defined with at least one hole for partially accommodating the LED. An inner surface of the reflector is coated to form a light reflecting surface. A flat lens includes a surface being treated with sand blast. A lamp housing has a receiving chamber for accommodation of the slim light emitting source, the reflector, the flat lens, and a driver. The lamp housing is formed with a plurality of heat dissipation fins. The driver is inserted in the other end of the receiving chamber of the lamp housing and has positive and negative leads connected to the slim light emitting source for enabling it to produce light.

  • Patent number: 7365154
    Abstract: The invention concerns antagonists of alphav-containing integrins which have therapeutic activity in oncology applications and methods for selecting such antagonists using a peptide which competes for alphaV-integrin binding with a known monoclonal antibody having demonstrated anti-tumor activity. The claimed peptide represents a conformational epitope or mimotope present on the ligand to which the therapeutic antibodies selectively bind.

  • Publication number: 20070235149
    Abstract: A door opening system includes a power transmission mechanism, a trolley, and a connecting arm. The power transmission mechanism includes a motor, a drive wheel driven rotatably by the motor, an indirect wheel, and a tension wheel. A transmission rope is trained on the drive, indirect and tension wheels in a closed loop such that parts of the transmission rope extend along a spiral path on the drive and indirect wheels, and do not contact each other, and such that rotation of the drive wheel drives the indirect and tension wheels rotatably. The trolley is coupled to the transmission rope, and is disposed between the indirect and tension wheels of the power transmission mechanism. The connecting arm has a first end coupled to the trolley, and a second end adapted to be coupled to the garage door.

  • Publication number: 20070234050
    Abstract: A communications system includes a transmitting device for processing packets to be sent, and a receiving device for processing the transmitted packets. The transmitting device includes a first memory unit, a first communications unit, and a first processing unit coupled therebetween. The first processing unit is operable so as to compose an initial packet segment, encrypt the initial packet segment, form a transmit packet, and enable the first communications unit to transmit the transmit packet. The receiving device includes a second communications unit, a second memory unit, and a second processing unit coupled therebetween. The second processing unit is operable so as to determine if there is any error in the transmit packet, decrypt the encrypted packet segment of the transmit packet, verify the transmit packet, and process the data transmitted in the transmit packet.
