| 20080223049 | Adaptive defrost control for frozen product dispensers - An adaptive defrost control for a frozen product machine implements an algorithm that utilizes various operating parameters of the machine to adaptively adjust the time interval between successive defrost cycles in a manner such that defrost cycles occur only on an as-needed basis. The adaptive defrost control minimizes the time during which the machine is in a defrost cycle, thereby maximizing the uptime of the machine during which frozen can be prepared. | 09-18-2008 |
| 20110162407 | Multiple barrel frozen product dispenser - A frozen product dispenser is characterized by at least two product freeze barrels for receiving product therein and for freezing the product for dispensing, and a refrigeration system for chilling the at least two barrels. The refrigeration system has at least two evaporators for and heat transfer coupled to each barrel, separate and controllable expansion valves each having an outlet coupled to an inlet to an inlet to an associated one of the evaporators, at least two compressors having outlets coupled to inlets to the expansion valves and inlets coupled to outlets from the evaporators, and at least one condenser in fluid circuit between outlets from the compressors and inlets to the expansion valves. The refrigeration system is controllable to selectively operate one or more of the compressors and one or more of the expansion valves in accordance with the cooling requirements of the barrels to provide an improved turndown ratio for improvements in efficiency of operation of the refrigeration system in response to changing cooling load requirements of the product barrels. | 07-07-2011 |

| 20090211269 | Adaptive beater and scraper speed control for frozen product dispensers - A controller for a drive motor for a scraper of a frozen product dispenser operates the drive motor to rotate the scraper at selected ones of a plurality of different speeds within a freeze barrel of the dispenser, in accordance with the values of sensed operating parameters of the dispenser. The arrangement provides for rotation of the scraper at speeds appropriate for, but no greater than required for, the then existent operating condition of the dispenser. | 08-27-2009 |

| 20120046678 | Over-the-Wire Valvulotomes - Over-the-wire self-sizing, self-centering valvulotomes sufficiently designed to cut valves through a wide range of vein diameters and adjust to the internal diameter of a vein as the valvulotome is being drawn through the vessel, and methods of use thereof during certain medical procedures that involve splitting valves, are disclosed herein. In an embodiment, an over-the-wire valvulotome includes a catheter having a proximal end, a distal end, and a longitudinal axis therebetween, wherein a first portion of a plurality of cutting tools engage the catheter at the distal end, and wherein an actuation mechanism engages the catheter at the proximal end; a retainer for temporarily shielding a second portion of the plurality of cutting tools, wherein the second portion includes cutting blades; and a sheath slidably moveable over the plurality of cutting blades, wherein the catheter and the retainer have internal diameters configured for passing over a guidewire. | 02-23-2012 |

| 20100095107 | METHOD AND APPARATUS FOR DEVICE DETECTION AND MULTI-MODE SECURITY IN A CONTROL NETWORK - A method and apparatus for device discovery and multi-mode security in a wired and/or wireless control network are described. A controlled device is configured with discovery-level instructions and application-level control instructions. The controlled device includes a user-configurable parameter for selecting between multiple security modes. In one or more security modes, the controlled device may ignore application-level messages until encrypted communications are established with a controller. In one mode, the encrypted communication is established with an encryption key exchange using a predetermined security key. In another mode, a specific key is manually entered into the controller by the user/administrator to facilitate the encryption key exchange. Additionally, for control applications where security is not important, an unencrypted security mode may be implemented. A driver ID provided by the controlled device facilitates loading of a preferred device driver by the controller. | 04-15-2010 |

| 20100115623 | SYSTEM AND METHOD FOR ENABLING DISTRIBUTION OF MEDIA CONTENT USING VERIFICATION - A system and method are provided to enable distribution of media content across a network using physical verification. The system includes a media server configured to send media content across a local network. A storage device can be in communication with the media server, and the storage device may store media content having encryption and provide the media content to the media server. A media reader that is in communication with the media server can be checked by the media server to determine whether a recording of the media content on removable physical media is loaded in the media reader in order to allow the media server to distribute the media content previously stored on the storage device. An output device can be enabled to receive media content from the media server and to reproduce the media content for an end user. | 05-06-2010 |
| 20100318198 | Automation Control of Electronic Devices - A system is provided for remote control of electronic devices. An automation controller can be used to control electronic devices via a network. A communication port for the automation controller is used to provide control signals for at least one electronic device via the network. An analog receiver module receives analog video signals from analog sources. A digital display module can receive a digital control interface from the automation controller. The digital control interface can include automation graphical interface controls. A display module, coupled to the automation controller, is used to composite the digital control interface received from the digital display module into a composite image with analog video signals. | 12-16-2010 |
