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, 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 and improved by employing dump iodide host tabular grains and, in forming the surface chemical sensitization sites, at least one silver salt epitaxially located on the tabular grains.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 dump iodide 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： Radiation-sensitive emulsions are disclosed comprised of high bromide tabular grains containing a peripheral band of increased iodide concentration. The tabular grains exhibit an average equivalent circular diameter of at least 2.0 .mu.m and are of a face centered cubic crystal lattice structure of the rock salt type. The tabular grains include central and peripheral regions extending between their major faces. The peripheral region is up to 0.2 .mu.m in width and contains an iodide concentration at least 2 mole percent higher than that of the central region measured at a location adjacent the peripheral region. Dislocations are present in the peripheral region to increase sensitivity and are minimized in the central region to maintain relatively constant sensitivities when pressure is applied locally.

摘要： A transponder measures temperatures and pressure within a pneumatic tire. A temperature count is transmitted, which is a function of temperature. A pressure count is transmitted, which is a function of both temperature and pressure. The pressure is determined by dividing the temperature count by the pressure count. Within the transponder, a timing generator generates a first timing window during which temperature is measured and a second timing window during which pressure is measured; a temperature register captures first data indicative of the temperature within the tire; a pressure register captures second data indicative of the pressure within the tire; and a modulator circuit impresses the first data as a first portion of a data stream on a signal output by the transponder, and impresses the second data as a second portion of the data stream on the signal output by the transponder. An oscillator outputs a signal having a first frequency which is indicative of the temperature within the tire during the first timing window, and having a second frequency which is indicative of the pressure within the tire during the second timing window. A register/counter circuit counts the oscillations of the oscillator signal during the first timing window to capture the first data in the first register, and counts the oscillations of the oscillator signal during the second timing window to capture the second data in the second register.

摘要： A radio frequency (RF) transponder (200) capable of measuring parameters associated with an object and transmitting data to an external reader/interrogator (106, 400). In use with a pneumatic tire (104), the transponder measures temperature and pressure within the tire. The transponder includes circuitry (226) for controlling windows of time (WT and WP) during which real-time temperature and pressure measurements are made, and for storing (236) calibration data, transponder ID number and the like, and for transmitting this information in a data stream (FIG. 3C) to the reader/interrogator. An excessive temperature condition may also be sensed (MTMS 218) and included in the data stream. The circuitry of the transponder is preferably implemented on a single IC chip (204), using CMOS technology, with few components external to the IC chip. The transponder is preferably passive, deriving its operating power from an RF signal provided by the exernal reader/interrogator. Data (NT) indicative of temperature and data (NP) indicative of pressure are both transmitted to the reader/interrogator, along with calibration data. A calibration data stored by the transponder and transmitted in the data stream is a slope of NT/NP, or the “ratioed” response of the temperature count divided by the pressure count, which is determined during calibration of the transponder.
