摘要:
A die for a thermal drop-on-demand fluid-ejection device includes thermal firing resistors, low-side switches, and high-side switches. The thermal firing resistors are organized over resistor groups such that each thermal firing resistor is located within only one of the resistor groups. The resistor groups are lesser in number than the thermal firing resistors. Each thermal firing resistor has a first end and a second end. The low-side switches are equal in number to the thermal firing resistors. Each low-side switch connects the second end of a corresponding thermal firing resistor to a low voltage. The high-side switches are equal in number to the resistor groups. Each high-side switch connects the first ends of the thermal firing resistors of a corresponding resistor group to power providing a voltage greater than the low voltage.

The present invention relates to fibre optics and more particularly to flexible, durable, fibre optic splices, and methods of installing such splices. One embodiment of the invention comprises a fibre optic splice comprising: a flexible central tensile member; a flexible helical wrapping positioned about the flexible central tensile member; and an outer protective jacket positioned about the flexible helical wrapping. The flexible central tensile member and the flexible helical wrapping define a splice enclosure to accommodate optical fibres of the splice, at least a portion of the optical fibres being arranged in a generally helical orientation within the splice enclosure.

A return label and tracking system is disclosed. The label of the present invention is a multi-layer label having a backing, a middle layer shipping label, and a top layer. The backing is pealed away to expose a permanent adhesive to affix the label to a box. The top layer is removably adhered to the shipping label. When a customer is ready to ship back an item, such as a depleted toner cartridge, for recycling or repair, the top layer can be removed to expose the shipping label, and the box can be shipped via a courier service or mail service. The shipping label is a variable label. The tracking system enables the receiver to determine which customer sent the item by having a record of which shipping labels were assigned to which customers. Thus, the customer can be credited for items returned.

A sub-pixel assembly of one embodiment of the invention is disclosed that includes a number of active display units. Each active display unit is capable of controlling light, and has a turn-on threshold responsive to a signal. The active display units are organized by their turn-on thresholds to achieve dithering of the light, in response to the signal.

A control circuit for a MEMS (Micro-Electro-Mechanical System) has a semiconductor switch which has a source, a drain and a gate, which is associated with a selected one of spatially arranged fixed and movable plates of a variable capacitor, and is arranged to selectively connect the selected one of the fixed and movable plates with a voltage source. A charge injection control circuit is associated with the semiconductor switch and attenuates current injection into the selected one of the fixed and movable plates of the capacitor.

Polynucleotide encoding modified HIV Env polypeptides are disclosed. The Env polypeptides are modified in the region of amino acids 420-436 so as to expose at least part of the CD4 binding region. Methods of diagnosis, treatment and prevention using the polynucleotides and polypeptides are also provided.
摘要:
A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to photo-thermocatalytic reactor design and scale-up. At low irradiance levels, the method is based on the implementation of low pressure drop biopolymeric and synthetic polymeric support for titanium dioxide and other band-gap media. At high irradiance levels, the method utilizes multifunctional metal oxide aerogels and other media within a novel rotating fluidized particle bed reactor.
