摘要:
In one aspect of the present invention, a light sensor is provided in the active pixel sensor cell for sensing incident radiation. The voltage corresponding to the photon-generated or other radiation-generated charge in the active pixel sensor cell is stored on a storage node via a sample-and-hold capacitor. Additional elements, such as source-follower transistors, may reside between the sensing element and the sample-and-hold capacitor. The signal is read via a readout source-follower (RSF) transistor. The readout source-follower drain is connected to the row select switch while its drain is connected to the output node on the column output bus. This configuration couples the storage node to the gate-source capacitance of the readout source-follower transistor. This allows the voltage on the storage node to increase proportionally to the increase in voltage on the readout node when the row select is closed and thus enables the drain current to flow through the RSF to the column output bus.

The herein disclosed processes provide a methodology for forming pre-cut gun wraps that may be formed specifically for a particular make and model of firearm or firearm accessory, and may be packaged and shipped to customer in a pre-cut form that allows for easy and adjustable non-permanent application to a firearm or firearm accessory. An exemplary embodiment of the herein disclosed processes includes the steps of: drawings a digital outline of a specific make and model of firearm; measuring a gun wrap surface area; translating the gun wrap surface area into a vector template; combining the vector template with digital artwork to determine a cut path; printing on an adhesive with the digital artwork; laminating the adhesive; cutting the pre-cut model specific gun wrap from the adhesive on a plotter/cutting machine using the cut path; and removing excess material from the pre-cut model specific gun wrap. The adhesive may be a pressure sensitive adhesive vinyl material.

Methods and apparatus relating to very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis.

A two-transistor (2T) pixel comprises a chemically-sensitive transistor (ChemFET) and a selection device which is a non-chemically sensitive transistor. A plurality of the 2T pixels may form an array, having a number of rows and a number of columns. The ChemFET can be configured in a source follower or common source readout mode. Both the ChemFET and the non-chemically sensitive transistor can be NMOS or PMOS device.

The invention is directed to apparatus and chips comprising a large scale chemical field effect transistor arrays that include an array of sample-retaining regions capable of retaining a chemical or biological sample from a sample fluid for analysis. In one aspect such transistor arrays have a pitch of 10 μm or less and each sample-retaining region is positioned on at least one chemical field effect transistor which is configured to generate at least one output signal related to a characteristic of a chemical or biological sample in such sample-retaining region. In one embodiment, the characteristic of said chemical or biological sample is a concentration of a charged species and wherein each of said chemical field effect transistors is an ion-sensitive field effect transistor having a floating gate with a dielectric layer on a surface thereof, the dielectric layer contacting said sample fluid and being capable of accumulating charge in proportion to a concentration of the charged species in said sample fluid. In one embodiment such charged species is a hydrogen ion such that the sensors measure changes in pH of the sample fluid in or adjacent to the sample-retaining region thereof. Apparatus and chips of the invention may be adapted for large scale pH-based DNA sequencing and other bioscience and biomedical applications.

摘要:
An exercise apparatus and method allows a user to perform exercises while seated or otherwise supported. Such exercises can assist in avoiding DVT and help those who otherwise might have difficulty exercising due to various conditions. The apparatus requires a base element formed of substantially flat sheet material dimensioned to accommodate a portion of a user's foot, and a leash element attached to a periphery of the base element and dimensioned for retention of the base element. The sheet material reduces friction between a user's foot and the exercise surface to allow a user to exercise their lower extremities via a sliding motion. The leash element allows the base element to be deployed to a floor or other surface for use, and then retrieved without requiring the user to bend over. The leash element is preferably formed of elastic to allow resistive forces to be applied to the base element.
