摘要:
Analyte filter arrays and methods for making an analyte filter array are provided. The arrays are formed using a dispersion of filter particles having selected moieties attached to the surface of the particles and a microarray having complementary moieties formed in an array on a substrate, such that each filter particle is attached to a selected region of the microarray. The moiety on the substrate may be RNA or DNA or other molecule. The substrate may be a surface of a detector array, a membrane that may be placed in registration with the detector array or a stamp used to transfer the filter array to a detector array.

Methods and sensors for detection and quantification of one or more analyte in a test sample are described. A response profile of an ion sensor to a control sample of a known interrogator ion is determined. The ion sensor is exposed to a test sample then to a second sample comprising the known interrogator ion, and a test sample response profile of the ion sensor is determined. One or more test sample sensor response profiles are compared with one or more control sensor response profiles for detecting, identifying, and quantifying one or more analytes in the test sample.

Spectroscopic filter arrays and methods for making spectroscopic filter arrays are provided. The arrays are formed using a dispersion of filter particles having selected moieties attached to the surface of the particles and a microarray having complementary moieties formed in an array on a substrate, such that each filter particle is attached to a selected region of the microarray. The moiety on the substrate may be RNA or DNA or other molecule. The substrate may be a surface of a photodetector array, a transparent plate that may be placed in registration with the photodetector or a stamp used to transfer the filter array to a photodetector array.

Projectile apparatus is provided employing light and sound that may be dispersed over a large area with high intensity to produce a non-lethal, visible and audible countermeasure to temporarily blind and/or disorient one or multiple potential adversaries. The apparatus is suitable for use in tactical scenarios by military, police, and special operations personnel. The apparatus is also suitable for use in training operations for military, police, and special operations personnel. For amusement or recreation, the apparatus may be used in simulated warfare or in games such as paintball.

An open top swing assembly uses a unique swing drive mechanism and a control to provide three selective swing height settings. The assembly has a frame which provides an open top structure for ease of access and a trapezoidal shaped front base to provide foot clearance. The swing drive mechanism includes a drive sleeve rotatably mounted to an axle that operatively supports the hanger. A drive flange is mounted on the axle, with a drive flange coupling device positioned between the sleeve and the drive flange to provide a limited lost motion connection. The coupling device includes a hub member coaxially and rotatably mounted on the axle and at least one torsional spring mounted coaxially on the hub member. The hub member includes abutments for engaging with the drive flange, whereby torque applied to the sleeve is transferred to the axle. A crank driven by a motor is linked to the sleeve to oscillate the sleeve. The swing height control device can have a sensor for detecting the swing height or amplitude. Preferably, three swing height settings are provided. The control device selectively outputs either no voltage, first, second or third predetermined voltages to selectively control the voltage input to the motor based on the selection of the swing height setting and/or the sensed swing height to achieve the selected swing height.

Detectors and methods for gathering, detecting and analyzing electromagnetic radiation are disclosed. A radiation detector includes one or more positive lenses to direct radiation to mirrors or to a photodetector. Coordinates of directed radiation are measured and interpreted to determine the angle of arrival. A color filter mosaic may be present to determine wavelengths of detected radiation. Temporal characteristics of the radiation may be measured.

A swing drive mechanism is provided for use with infant's and child's swings. The swing drive mechanism provides an input mechanism, an output mechanism, and a torsion spring member disposed between the input mechanism and the output mechanism. The torsion spring member includes a first portion and a second portion that interact together to produce a desirable spring gradient while also reducing the overall length of the torsion spring member. The torsion spring member is secured into attachment with the input mechanism by a novel securement mechanism. The output mechanism includes an axle and a drive flange. Preferably, the features of the input mechanism, the output mechanism, and each portion of the torsion spring member are integrally formed.
