Patent number: 8339086Abstract: Presented is a system for synchronizing movement of roller shades each from a first position to a common second position. The system includes a master controller, a plurality of optical assemblies each configured to obtain information related to the position of one of the roller shades, and a plurality of motor assemblies. Each of the motor assemblies is configured for receiving the position information from one of the plurality of optical assemblies, receiving a master shade movement time from the master controller, and moving one of the of roller shades from the first position to the common second position in response to the received position information so that the roller shade arrives at the common second position simultaneously with the other roller shades in a time equal to the master shade movement time.Type: GrantFiled: October 26, 2010Date of Patent: December 25, 2012Assignee: Crestron Electronics Inc.Inventors: George Feldstein, Mark LaBosco

Patent number: 8339085Abstract: Presented is a method for synchronizing movement of a plurality of roller shades each disposed at a first position to a common second position. The method includes obtaining information related to the position of each of the plurality of roller shades with a respective one of a plurality of optical assemblies, and moving each of the plurality of roller shades from the first position to the common second position in response to the respective obtained position information so that each of the plurality of roller shades arrives at the common second position at the same time.Type: GrantFiled: October 26, 2010Date of Patent: December 25, 2012Assignee: Crestron Electronics Inc.Inventors: George Feldstein, Mark LaBosco

Patent number: 8316027Abstract: Presented is a method for obtaining a single set of media search results from a search of media sources. The method includes providing a search query, executing a search of each of the media sources for media based on the provided search query, generating results of the searches, and consolidating the results of the searches into the single set of search results that include a list of media items with associated metadata. The method further includes organizing the media items into groups. Each of the groups includes media items that have similar content. The similarity of the content is defined by the media items' associated metadata meeting a metadata matching threshold. The method further includes filtering the groups, sorting the groups of media items with respect to each other, sorting the media items within the groups, and displaying the groups of media items.Type: GrantFiled: March 12, 2010Date of Patent: November 20, 2012Assignee: Creston Electronics Inc.Inventor: John Pavlik

Patent number: 8254838Abstract: A portable RF wireless device (41), such as a microphone, is provided with an infrared beacon in order to signal a connection request to a wireless communication access point (48) using a first IR code (401). In response to this first IR code, the wireless communication access point broadcasts an RF inquiry message (101) that is responded (102) to by the portable RF wireless device in order to establish an RF communication link. After the RF communication link is established, the portable RF wireless device conditionally transmits a second IR code to verify that it is still collocated in the local vicinity of the wireless communication access point, such as being in the same room.Type: GrantFiled: May 15, 2009Date of Patent: August 28, 2012Assignee: Crestron Electronics Inc.Inventor: George Feldstein

Patent number: 8195091Abstract: A teacher microphone (30) is provided with an infrared (IR) transmitter to signal a connection request to a wireless audio access point (50) using a first IR request inquiry signal (331). In response to this first IR code, the wireless audio access point establishes a first RF communication link (300). After the first RF communication link is established, the teacher microphone conditionally transmits a first IR presence signal (332) to verify that it is still collocated in the local vicinity of the wireless audio access point, such as being in the same room. The wireless audio access point is capable of maintaining a connection with additional portable wireless devices, such as a student microphone (40).Type: GrantFiled: March 26, 2010Date of Patent: June 5, 2012Assignee: Crestron Electronics Inc.Inventors: George Feldstein, Frankie Chow

Patent number: 8190095Abstract: A wireless communication access point is provided with an infrared beacon transmitter to signal a connection request to a portable wireless device, such as a microphone, using an IR room code. In response to this IR room code, the portable wireless device broadcasts a RF inquiry message that is responded to by the wireless communication access point in order to establish a RF communication link. After the RF communication link is established, the wireless communication access point periodically transmits the IR room code to verify that it is still collocated in the local vicinity of the portable wireless device, such as being in the same room.Type: GrantFiled: May 12, 2010Date of Patent: May 29, 2012Assignee: Crestron Electronics Inc.Inventor: George Feldstein

Patent number: 8181747Abstract: A bicycle sprocket chain cleaning and lubrication apparatus allows a sprocket chain (3) to be cleaned while still mounted on the bicycle. The apparatus includes a includes a housing (10) for enclosing the sprocket chain on all sides consisting of mutually connectable upper half-shell (11) and lower half-shell (12) portions and a securement assembly which includes a mounting plate adapted to attach to a rear wheel quick disconnect of the bicycle. The housing is suspended from the sprocket chain and provides a funnel shaped solvent hopper (17), a hose connection (21) to a compressed air supply, and an air knife (23) adapted to direct high velocity air to impinge upon and thereby dry the sprocket chain.Type: GrantFiled: October 29, 2008Date of Patent: May 22, 2012Assignee: Crestron Electronics Inc.Inventor: George Feldstein

Patent number: 8150074Abstract: An impedance matched connection is provided between a load and a power source that outputs signals within a predetermined frequency range. A coaxial line has a predetermined characteristic impedance and an inner conductor, an outer conductor, and an insulator the two conductors. Each conductor has a first end electrically connectable to output terminals of the power source. A compensation circuit has an adjustable impedance, a first terminal electrically connected to a second end of the inner conductor and to a first terminal of the load, and a second terminal electrically connected to a second end of the outer conductor and to a second terminal of the load. The compensation circuit is sufficiently adjustable to attain, for a pulse having a rise time/fall time faster than those associated with the predetermined range of frequencies, a combined impedance and load that is substantially equal to the characteristic impedance of the coaxial line.Type: GrantFiled: August 8, 2008Date of Patent: April 3, 2012Assignee: Crestron Electronics Inc.Inventors: George Feldstein, Krunoslav Esteban Draganovic

Patent number: 7928917Abstract: An electrical device configured to install within a wall mounted electrical box includes an antenna bezel frame, an antenna element, and a radio frequency circuitry component. At least a portion of the antenna bezel frame is configured to protrude through an opening in a faceplate. The antenna element is mounted to the antenna bezel frame such that the antenna element is located a distance forward of a plane that contains a front surface of the faceplate when the field configurable electrical device is installed. The radio frequency circuitry component is in electrical communication with the antenna element and is configured to receive a control signal from the antenna element.Type: GrantFiled: April 9, 2010Date of Patent: April 19, 2011Assignee: Crestron Electronics IncInventors: George Feldstein, Stan Wisniewski, Philip Bellingham, Krunoslav Draganovic
