Patent number: 6399700Abstract: Synthetic comb copolymers which elicit controlled cellular response, methods of applying these polymers to various surfaces, and methods of using the polymers for modifying biomaterial surfaces, in tissue engineering applications and as drug delivery devices are provided. The comb copolymers are comprised of hydrophobic polymer backbones and hydrophilic, non-cell binding side chains which can be end-capped with cell-signaling ligands that guide cellular response. By mixing non-cell binding combs with ligand-bearing combs, the surface concentration and spatial distribution of one or more types of ligands, including adhesion peptides and growth factors, can be tuned on a surface to achieve desired cellular response. In one embodiment, the combs are used as stabilizing agents for dispersion polymerization of latexes. The comb-stabilized latexes can be applied to substrates by standard coating operations to create a bioregulating surface, or used as drug delivery agents.Type: GrantFiled: March 26, 2001Date of Patent: June 4, 2002Assignee: Massachusetts Institute of TechnologyInventors: Anne M. Mayes, Linda G. Griffith, Darrell J. Irvine, Pallab Banerjee, Terry D. Johnson

Patent number: 6029608Abstract: The invention is an animal containment device for the transportation, holding, feeding, watering, and caring for of animals. The device is designed to maintain adequate temperature, humidity, ventilation, and sanitary conditions. The device includes a ventilation device which can operate in negative, positive, or atmospheric pressure modes. The device also includes a multi-level waste and by-product removal device. The waste and by-product removal device consists of multiple slotted layers through which liquids and solids will pass. These liquids and solids will be collected on different layers upon which they can be dried and easily removed. This device eliminates odor and contamination within the device. The device allows for special handling, the ability to isolate/quarantine, and the ability to provide easy animal ingress/egress.Type: GrantFiled: July 30, 1998Date of Patent: February 29, 2000Inventor: Terry D.

Patent number: 5319702Abstract: Methods and apparatus for use in conjunction with a telephone or with equipment in telecommunication with a remote telephone are disclosed. The apparatus provides an indication as to whether a remote party using the remote telephone has performed a specific act causing the generation of a hook flash-type signal which is detected by the apparatus. The apparatus includes a low pass filter for passing energy having frequencies below about 500 Hz, and energy detector for detecting a specific electrical energy pulse having been filtered by the low pass filter and having a predetermined minimum magnitude. The apparatus also includes software for cooperating with the energy detector to detect a specific event(s) occurring on the telephone line during a predetermined maximum time window following the detection of a specific pulse. The detection of the specific event(s) provides an indication as to whether the remote party has performed a specific act such as attempting to initiate a 3-way conference call.Type: GrantFiled: July 29, 1992Date of Patent: June 7, 1994Assignee: Tele-Matic CorporationInventors: Dwight W.

Patent number: 4506465Abstract: Apparatus and method for snow removal is disclosed. A wheeled frame having an adjustable suspension capable of operation in a snow removal and a transport position is provided. The frame is open at one end and includes a hitch at the other end for connection to a prime mover. Two vertical snow cutting knives are connected to the frame near the open end thereof with a horizontal snow cutting knife connecting the vertical knives proximate the ground. A snow moving blade is pivotably supported to the frame and actuated by a pair of double acting cylinders to move up and down. In operation the open end of the apparatus is pushed into a pile of snow and snow is cut loose by the knives. The blade is then lowered into close proximity with the ground and near the open end of the frame whereby a selected quantity or block of snow may be pulled or towed away.Type: GrantFiled: December 22, 1982Date of Patent: March 26, 1985Assignee: Melvin L.

Patent number: 4067297Abstract: In a self cleaning enclosure for production of livestock including hogs an enclosed slightly conical circular surface is disclosed which includes a scraper extending radially outward over the enclosed surface and rotational over the surface to effect cleaning and sanitization of the surface. The scraper includes a conveyor system out of direct contact with the surface which carries the waste material outward along the scraper to a trench encircling the enclosed surface and serving as a depository for the waste. A trench scraper is carried with the surface scraper, and extends into the trench for moving the waste to a localized outlet for removal of the waste from the trench. A motor caused rotation of the scraper around the surface and also causes operation of the conveyor system.Type: GrantFiled: August 2, 1976Date of Patent: January 10, 1978Inventor: Terry D. Johnson
