A touch sensor includes a resistive layer on a substrate and electrodes on the resistive layer. The electrodes and portions of the resistive layer between the electrodes form series resistor chains disposed at peripheral regions of the touch sensor and surrounding a touch region of the touch sensor. The electrodes are formed by forming a conductive layer on the resistive layer in a thin-film deposition process, followed by patterning the conductive layer into the electrodes. A sheet resistivity of the resistive layer is between about 200Ω and about 800Ω. A sheet resistivity of the conductive layer is between about 0.03Ω and about 0.2Ω. A ratio of the sheet resistivity of the resistive layer to the sheet resistivity of the conductive layer is between about 2,500 and about 10,000.

Techniques for providing multi-user multi-touch projected capacitive touch sensors are disclosed herein. Some embodiments may include a method that includes receiving a first sense signal from a first sensing array, the first sensing array configured to provide the first sense signal indicating a first touch on a first touch surface of a touch substrate as well as receiving a second sense signal from a second sensing array, the second sensing array configured to provide the second sense signal indicating a second touch on a second touch surface of a second touch substrate occurring concurrently to the first touch. The method may further include determining whether the first touch and the second touch share at least one anti-ghost. The method may also include associating the first touch and the second touch with a common touch entity in response to determining that the first touch and the second touch share the at least one anti-ghost.

Multi-user multi-touch projected capacitance touch sensor with event initiation based on common touch entity detection

Embodiments include a method and system for projected capacitive (PCAP) touchscreen construction with laser ablation. In glass/film/film (GFF) PCAP touchscreens, the films are coated with indium-tin-oxide (ITO), patterned by printing silver ink, and by ablating both the ITO and silver with a laser. A similar process occurs for a glass/glass (2GS) PCAP touchscreen. Embodiments include varying the pattern with which the laser ablates ITO on film within the touch area to improve touchscreen sensitivity. For example, by varying the width of patterns of floating ITO islands such that widths are less than or equal to a plan-view electrode gap between vertical and horizontal electrode pads and larger elsewhere, the touch sensitivity of the PCAP touchscreen may be improved and/or maximum touchscreen size may be increased.

Determining a state of a fungal spore includes defining types of fluorescent biomolecules of interest within the spore. Color characteristics of fluorescent light corresponding to excitement of the fluorescent biomolecules of interest under UV light are stored. Air including the fungal spore is directed to a collection cartridge and trapped. The spore is illuminated with light including UV light. A color image of the spore is captured and analyzed to estimate concentrations of the fluorescent biomolecule of interest. The state of the spore is determined from the estimated concentrations.

Spore state discrimination

Various configurations and arrangements for touchscreens are disclosed to accommodate for one or more optical discontinuities that can be present within these touchscreens. When the one or more optical discontinuities are present, these configurations and arrangements of the touchscreens present a single layer of transparent conductive material that can be difficult to perceive by a human eye when viewing the touchscreens. Additionally, various edge correction techniques are disclosed to adjust mutual capacitances along a perimeter of the touchscreens. These edge correction techniques adjust mutual capacitances such that the values of the mutual capacitances are substantially uniform throughout.

Projected-capacitive (PCAP) touchscreen

A device includes a camera sensor and an illumination source structure. The illumination source structure is positioned to emit light towards a field of view of the camera sensor. The illumination source structure includes a bore, internal threads extending along at least a portion of a length of the bore, and a light emitting diode (LED) positioned within the bore such that the internal threads encircle a lens of the LED.

A location of contact with a touch sensitive device is determined. Output signals associated with a plurality of electrodes such as formed on a single layer of the touch sensitive device are measured to identify a first electrode positioned at an approximate location of contact with the touch sensor. An output signal associated with a different electrode that is separated from the first electrode is measured to determine an undesired signal amount, such as due to deflection. An undesired single amount associated with the first electrode may be estimated based on the undesired signal amount measured at the other electrode. The signal amount measured at the first electrode is then compensated by the estimated undesired signal amount. The location of contact with the touch sensor is then determined based on the compensated signal amount.

An airborne biological particle monitoring device collects particles floating in air. The monitoring device includes a processor, a camera sensor, and a set of approximately monochromatic illumination sources that correspond to a set of spectral curves. The camera sensor captures images of the particles providing a spectral analysis of the particles. The processor analyzes the images to identify the collected particles.

A flow of air including a fungal spore is directed to a collection cartridge. The fungal spore is trapped within the collection cartridge. The fungal spore is illuminated with ultraviolet (UV) light and a camera shutter associated with a camera sensor is opened for a time period. The camera sensor is allowed to collect light emitted from the fungal spore during a first portion of the time period. After the first portion of the time period has elapsed, a first burst of visible light originating from a first position is directed towards the fungal spore during a second portion of the time period. A second burst of visible light originating from a second position is directed towards the fungal spore. After the second portion of the time period has elapsed, the camera shutter is closed to generate an image. The image is analyzed to obtain a shape of the fungal spore.

Touchscreen with overlapping floating transparent conductive islands

A particle monitoring device includes a camera sensor for imaging particles, a set of light sources, and an optical component. A first light source provides light of a first color component. A second light source provides light of a second color component. The optical component receives light of the first color component in a first direction from the first light source, and redirects the light of the first color component in an output direction towards the particles to illuminate the particles using light of the first color component. The optical component receives light of a second color component in a second direction, different from the first direction, from the second light source, and redirects the light of the second color component in the output direction towards the particles to illuminate the particles using light of the second color component.

Hyper-spectral imaging of airborne biological particles

Embodiments enhance graphic capabilities in projected-capacitive (PCAP) touch sensitive systems, and more specifically to a border component of a PCAP touchscreen. Embodiments include a method and an apparatus for a PCAP touchscreen layered structure. Some embodiments include screen printing a border component on a cover sheet, curing the border component, ablating a pattern on the border component, and screen printing one colored ink onto the pattern on the border component. In some embodiments the border layer is black, and the colored ink is coupled to a cover sheet. The pattern causes the colored ink to appear as a continuous gradient of the colored ink. In some embodiments the border component includes two or more border-layer components. At least one of the border-layer components may include an ablated pattern. Each ablated pattern may be coupled to a different colored ink.
