Abstract:
A foldable or collapsible cart can be oriented in several different configurations to accommodate different loads and transport requirements. In one configuration, the cart may be folded for direct load the back of a vehicle. In another configuration, the cart can operate in lowboy or dolly mode. In another configuration the cart may be used as a hand truck.
Abstract:
An electro-optic display (1) includes an electro-optic medium, a pixel electrode (10) for applying an electric field to the medium and a column electrode (6) associated with the pixel electrode. To reduce power consumption, when it is necessary to change the voltage on the column electrode (6) from a first value to a second value to change the optical state of the electro-optic medium, the column electrode voltage is first changed to a third value intermediate the first and second values to permit charge to flow to or from the column electrode, and thereafter the column electrode voltage is changed from the third voltage to the second voltage.
Abstract:
A multi-color electrophoretic medium contains first, second and third species of particles, the particles having substantially non-overlapping electrophoretic mobilities and bring of three different colors, one of which is white. The particles are dispersed in a fluid having a fourth color. A method for driving such a display is also described.

Abstract:
A tip (41) for use with a lancing device (11). A wall extends upwardly from a base and forms a substantially saddle-shaped distal surface for interfacing with a patient's skin. An opening (43) extends entirely through the tip. The tip (41) is movably received by a pressure sleeve assembly. The pressure sleeve assembly includes a housing (37) and a pressure sleeve movable between first and second positions. A spring (35) is connected between the housing (37) and the pressure sleeve. A lancet (21) is rigidly fixed to the housing (37) and is covered when the pressure sleeve is in the first position and exposed through the substantially saddle-shaped distal surface (42) of the tip (41) when the pressure sleeve is in the second position. The substantially saddleshaped distal surface (42) gathers the patient's skin toward the center of the tip to facilitate expressing blood from a lanced site.
Abstract:
A cart is disclosed which is capable of being wheeled to a vehicle and mounted thereon through a mount secure coupling attached to the cart and a secure receiver attached to the vehicle. Upon secure attachment to the vehicle, the carts undercarriage assembly including wheels are capable of being retracted into the top deck assembly of the cart. Therefore, the vehicle maintains clearance from the road even after the cart is attached. Upon reaching a destination, the undercarriage of the cart is lowered and the cart is detached from the vehicle. The cart is then able to be wheeled away. The cart allows for transportation of loads without the need for the operator to actually carry either the load or the cart at any stage from start to finish or perform any additional steps to safe and securely attach the cart to the vehicle
Abstract:
A process for producing a color electro-optic display uses a sub-assembly (100; 200; 300; 402) comprising an electro-optic layer (106) and a light-transmissive electrically-conductive layer (104). This sub-assembly is laminated to a backplane (404, 408) bearing electrodes with the electro-optic layer (106) disposed between the backplane (404, 408) and the electrically-conductive layer (106). A flowable material is placed over the sub-assembly (100; 200; 300; 402) and a color filter array is placed over the electrically-conductive layer (106) and aligned with the electrodes of the backplane (404, 408) to form the color display.
Abstract:
A photovoltaic roofing tile has a substrate, a photovoltaic laminate positioned over the substrate, and a fire suppression material arranged proximate a first end of the substrate. A plurality the photovoltaic roofing tiles are arranged on a roof deck in an overlapping relationship.
Abstract:
A method for producing a photovoltaic roofing tile includes providing an open compression tool and placing an undulated formed polymeric substrate in the open compression tool as well as placing a substantially flat photovoltaic laminate in the open compression tool proximate the substrate. Heat and pressure are applied to the photovoltaic laminate to simultaneously bond the photovoltaic laminate with the substrate and impart undulations to the photovoltaic laminate which correspond to undulations in the substrate. The heat and pressure are applied by closing the compression tool to apply heat from the compression tool to the photovoltaic laminate and to compress the photovoltaic laminate and the substrate against one another.
Abstract:
An electro-optic display comprises a backplane; a layer of electro-optic material disposed adjacent the backplane; a protective layer; and a sealing layer of a metal or a ceramic extending between the backplane and the protective layer, and thus sealing the layer of electro-optic material from the outside environment.
