Abstract: A medical device such as a cannula, catheter, needle or biosensing probe includes an elongated body for penetrating, inserting and/or positioning in or through the skin of a patient. The elongated body has an outer surface that when positioned in the patient with a coefficient of friction sufficient to inhibit movement between the elongated body on the skin at the insertion site to inhibit irritation at the infusion site. A lubricious coating is provided on the elongated body to assist in penetration and/or insertion of the elongated body into the patient. The lubricious coating can be removed by a shearing action by the insertion of the elongated body into the patient and/or by absorption of the lubricious coating to expose the outer surface of the elongated member.

Abstract: A method of calibrating an image sensor may include detecting a response from a pixel of the image sensor as a result of light having an intensity impinging on the pixel, and measuring the actual standard deviation of the response of the pixel at the intensity of light. The method may also include determining an averaging number for the pixel at the intensity. The averaging number may be a number of responses of the pixel at the intensity to be averaged to attain an average response having a standard deviation less than or equal to a target value. The method may further include determining the average response of the pixel using the determined averaging number.

Abstract: In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.

Abstract: A pixel circuit with a dual gate PMOS is formed by forming two P+ regions in an N? well. The N? well is in a P+ type substrate. The two P+ regions form the source and drain of a PMOS transistor. The PMOS transistors formed within the N? well will not affect the collection of the photo-generated charge as long as the source and drain potentials of the PMOS transistors are set at a lower potential than the N? well potential so that they remain reverse biased with respect to the N? well. One of the P+ regions used to form the source and drain regions can be used to reset the pixel after it has been read in preparation for the next cycle of accumulating photo-generated charge. The N? well forms a second gate for the dual gate PMOS transistor since the potential of the N? well 12 affects the conductivity of the channel of the PMOS transistor. The addition of two NMOS transistors enables the readout signal to be stored at the gate of one of the NMOS transistors thereby making a snapshot imager possible.

Abstract: A variable resolution imager and method of forming output signals from a variable resolution imager are described. An imager having a number of pixels is provided. The variable resolution imager is accomplished by binning selected groups of pixels in various sections of the imager together, thereby forming regions of variable resolution. The larger the number of pixels binned together the lower the resolution of that section of the imager. The binning is controlled by programming signals to the imager so that the resolution can be changed within a frame or between frames. The resolution can be controlled by a computer processor or by an operator. Feedback of the output of the imager can be used to determine the resolution of various sections of the imager.
