摘要： Communications between an RFID interrogator and an RFID transponder require that no more than one transponder be present in the reading range of the interrogator and transmitting into motion at any given time. If multiple transponders are in the field, then a collision between the return signals of the transponders occurs, rendering the signals unreadable. A method to resolve the collisions and allow for accurate transmission of each transponder's data is given. This method is especially effective over other methods when the transponder is a read-only type of device, whereby there is no communications interrogator on board the read-only transponder.

摘要： An improved spectrally sensitized ultrathin tabular grain emulsion is disclosed in which tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide and at least 0.25 mole percent iodide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, (e) exhibiting an average thickness of less than 0.07 .mu.m, and (f) having latent image forming chemical sensitization sites on the surfaces of the tabular grains, are spectrally sensitized. The speed-granularity relationship of the emulsion is improved by employing in forming the surface chemical sensitization sites at least one silver salt epitaxially located on tabular grain surface sites that contain increased iodide concentrations.A photographic element is disclosed comprised of a support, a first silver halide emulsion layer coated on the support and sensitized to produce a photographic record when exposed to specular light within the minus blue visible wavelength region of from 500 to 700 nm, a second silver halide emulsion layer capable of producing a second photographic record coated over the first silver halide emulsion layer to receive specular minus blue light intended for the exposure of the first silver halide emulsion layer, the second silver halide emulsion layer being capable of acting as a transmission medium for the delivery of at least a portion of the minus blue light intended for the exposure of the first silver halide emulsion layer in the form of specular light, wherein the second silver halide emulsion layer is comprised of the improved spectrally sensitized ultrathin tabular grain emulsion of the invention.The ultrathin tabular grain emulsions with silver salt epitaxy chemical sensitization have been observed to produce larger than expected speed increases, to produce higher than expected contrasts, to be unexpectedly specularly transmissive and therefore compatible with forming sharp photographic images in underlying emulsion layers, to exhibit a higher percentage of total light absorption in the wavelength region of maximum absorption by the spectral sensitizing dye or dyes employed, and to exhibit a surprising tolerance of inadvertent manufacturing variances.

摘要： A hook setting apparatus which supports a fishing rod and is triggered responsive to the fish jerking on the bait secured to the rod through a fishing line. The apparatus includes a support member disposed in the substantially upright position which pivotally carries on its end portion a second member which supports a rod holder. A spring assembly biases the second member in a predetermined pivotal direction for setting the hook in the fish's mouth. A trigger assembly which is mounted on the support member maintains a second member in a predetermined pivotal position by counteracting the forces applied to the second member by the tension spring assembly. The trigger assembly releases the second member responsive to a fish jerking on the fishing pole such that the tension spring assembly thereby sets the hook in the fish's mouth. The force required to trigger the device can be adjusted such that fishes of various sizes will activate the device.

摘要： The present invention is directed to a method of forming a positive image in a photothermographic element comprising a potentially negative-working emulsion wherein fog density development is imagewise inhibited in exposed areas of the image upon thermal development, the element further comprising a developer or precursor thereof and an oxidized developer scavenging agent to accelerate development by removing oxidized developer as it is formed during the thermal development step. In one embodiment of the invention, in which a density-inhibiting agent is released during thermal development that inhibits the thermal development of unexposed silver salts in the exposed areas relative to the unexposed areas, the method comprises imagewise exposing the film with a non-solarizing amount of radiation/energy to form a latent image and thermally developing the latent image in a single development step to produce a positive image in the element. The present invention is also directed to a photothermographic element that can be used in the present process in which a positive image characterized by high speed and discrimination is formed when exposed and thermally heated above 150° C.

摘要： A process is disclosed of conducting in a single reaction vessel selective site high chloride epitaxy deposition as a continuation of host high bromide {1111} tabular grain emulsion precipitation. A host tabular grain emulsion is precipitated accounting for 0.05 to 1.5 moles of silver per liter of dispersing medium. Any iodide at the major faces of the tabular grains is uniformly distributed and any iodide in a surface region of the grains amounts to less than 7 mole, based on silver in the surface region. Until epitaxy is formed, pH is held in the range of 3 to 8. Gelatino-peptizer in an amount of 1 to 40 grams per Ag mole is added to the emulsion. Chloride ion in a range of from 0.03 to 0.15 mole per liter is dispersed in the emulsion. pBr is held in the range of from 3.0 to 3.8 until epitaxy is formed. Iodide ion in a concentration of from 5.times.10.sup.-6 to 1.times.10.sup.-4 mole per square meter of grain surface area is uniformly adsorbed to the major surfaces of the tabular grains.
