摘要:
A protective enclosure is disclosed for an interactive flat-panel control device. The protective enclosure is watertight, crush-resistant, and impact-resistant. An electrical adapter may disposed within the protective enclosure and covered with an elastomeric covering that permits a connector of the adapter to flex with respect to the lower shell of the enclosure so that the connector may easily be inserted into an interface jack of the electronic device. The elastomeric covering also provides a watertight seal that enables the protective enclosure to be submersibly watertight. While providing protection, the protective enclosure simultaneously allows smooth and accurate interaction with the interactive flat-panel controlled device. The protective enclosure has a protective membrane that permits RF and touch screen stylus inputs, as well as capacitance, such as from a finger, to be transmitted accurately to the flat-panel control. The hardness and texture of the protective membrane allows a stylus or finger to glide smoothly along the surface of the membrane without catching or sticking. The protective enclosure is further adapted to allow infrared and other communication signals while the device is secured inside the case. Further, electrical connections can be made through the case without affecting the protection afforded the electronic device inside. The protective enclosure may have a removable cable management belt clip that has a flange that retains and prevents entangling of an accessory cable for the interactive flat-panel control device.

The present invention provides mineralized hydrogels and methods of making and using mineralized hydrogels, by combining a first mixture including a calcium derivative, a second mixture including a phosphate derivative and a hydrogel to form a calcium phosphate dispersion containing the hydrogel. The hydrogel in the calcium phosphate dispersion are crosslinked to form a mineralized hydrogel, in which calcium phosphate minerals are substantially uniformly dispersed within the hydrogel.

The present invention provides blend water-swellable materials and hydrogels suitable for use in biomedical or other applications. The blend water swellable materials and hydrogels have at least one hydrophilic polymer and at least one other polymer or oligomer having both hydrophobic and hydrophilic recurring units where the blend phase separates and is opaque and immiscible in the presence of water. Methods of making these blend water-swellable materials and hydrogels are also described.
摘要:
Inter-process communications between a first process and a second process are secured. A first process recognizes that inter-process communications must be initiated with a second process. A first computer that supports the first process submits a request to initiate inter-process communications with a second computer that supports the second process. The second computer replies to a request to initiate inter-process communications by replying to the first computer with a request for information of a digital certificate that authenticates the first process.
摘要:
A protection circuit for use with a charger and a chargeable element, such as a rechargeable lithium ion battery, comprises a shunt regulator having a threshold ON voltage coupled in parallel across the chargeable element, and a temperature-dependent resistor, e.g., a positive temperature coefficient device, coupled in series between the charger and the chargeable element. The temperature dependent resistor is thermally and electrically coupled to the shunt regulator, wherein the first variable resistor limits current flowing through the shunt regulator if the current reaches a predetermined level less than that which would cause failure of the regulator, due to ohmic heating of the regulator.

Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a cyan coupler having the formula: wherein: the term “NB coupler” represents a coupler of formula (I) that forms a dye with the developer 4-amino-3-methyl-N-ethyl-N-(2-methanesulfonamidoethyl) aniline sesquisulfate hydrate for which the left bandwidth (LBW) using spin-coating is at least 5nm less than that of the same dye in solution form; V is a sulfone, sulfoxide or sulfonamide-containing group; Y is H or a coupling-off group; each Z1, Z2, Z3 and Z* are an independently selected substituent group where p is 0 to 2; provided that Z1, and Z2 or Z2 and Z3 can join to form a ring; provided further that Z1, and Z2 do not join to form an aromatic or heterocyclic ring; and provided further that the combined sum of the aliphatic carbon atoms in V, all Z′, Z″ and all Z* is at least 8.
摘要:
A photographic element is disclosed comprising a silver halide emulsion layer having associated therewith an acetanilide based yellow dye forming coupler and a compound of the following Formula I: wherein R1, R2 and R3 are each independently aromatic, cyclic, linear, or branched chained hydrocarbon groups. The invention provides photographic elements which exhibit exceptional yellow dye light stability, and which retain desirable properties derived from the use of acetanilide based yellow dye-forming couplers, particularly when used in combination with substituted phenolic and/or thiomorpholine dioxide stabilizers. In addition to stabilizing properties, compounds of Formula I have organic solvent properties, and accordingly may be advantageously used partly or totally in place of conventional high boiling permanent and/or auxiliary organic coupler solvents to disperse the acetanilide-based couplers.

Disclosed is a color photographic element comprising a yellow dye-forming coupler having formula I: wherein: B is a substituent containing 6 or more carbon atoms; L is a linking group bonded to the anilide ring by a carbon, sulfur, or oxygen atom; R is a substituent and n is 0-3; X is a solubilizing group containing an acidic proton; Y is a substituent; and Z is selected from the group consisting of H, chloro, an alkoxy group and an aryloxy group. The element provides an improved combination of reactivity and stability.
摘要:
A photographic element is disclosed comprising a support bearing at least one light sensitive silver halide emulsion layer comprising a dispersion of a dye-forming coupler and a water-insoluble polymer, wherein the polymer has a glass transition temperature of less than 75.degree. C. and is formed from at least 30 wt % monomer units which provide the polymer with functional groups that are hydrogen bond donors. The combination of such relatively low T.sub.g polymers with couplers in photographic elements leads to both decreased pressure sensitivity and improved image-dye light stability, as well as a decreased tendency toward dye smear or thermal induced change. The advantages of the invention are particularly useful for yellow coupler dispersions used in photographic color paper elements on reflective supports, although they will also be useful for motion picture print film and other projection or display films on transparent or diffuse supports.
摘要:
An overcurrent protection system which will give a rapid response to relatively small overcurrents. The system, which can be connected between an electrical power supply and an electrical load to form an operating circuit, and which when so connected protects the circuit from overcurrents, has a normal operating condition and a fault condition, and comprises: a circuit interruption element having, (1) a normal state which permits the flow of a normal current, I.sub.NORMAL, when the system is in the normal operating condition, and (2) a fault state which permits the flow of at most a reduced current, substantially less than I.sub.NORMAL, when the system is in the fault condition; and a control element, connected in series with the circuit interruption element, the control element having a variable resistance which (1) is low when the current in the system does not exceed the normal current, I.sub.NORMAL, by a predetermined current amount, and (2) increases by at least a predetermined resistance amount when the current in the system exceeds the normal current, I.sub.NORMAL, by the predetermined current amount; the circuit interruption element changing from its normal state to its fault state, thereby causing the system to change from its normal operating condition to its fault condition, when the resistance of the control element has increased by the predetermined resistance amount.
