Abstract: A delivery device for an active agent comprises nanoparticles based on a biopolymer such as starch. The delivery device may also be in the form of an aptamer-biopolymer-active agent conjugate wherein the aptamer targets the device for the treatment of specific disorders. The nanoparticles may be made by applying a high shear force in the presence of a crosslinker. The particles may be predominantly in the range of 50-150 nm and form a colloidal dispersion of crosslinked hydrogel particles in water. The biopolymer may be functionalized. The aptamer may be conjugated directly to the cross-linked biopolymers. The active agent may be a drug useful for the treatment of cancer. The delivery device survives for a period of time in the body sufficient to allow for the sustained release of a drug and for the transportation and uptake of the conjugate into targeted cells. However, the biopolymer is biocompatible and resorbable.

Abstract: A system adjusts detection parameters used to process a signal from a PIR sensor to reduce false triggers. A detection module receives a sensor output signal from a PIR sensor and inputs from environmental sensors, including a temperature sensor. The detection module adjusts detection parameters of a bandpass filter and/or a thresholod comparison module based on the inputs from the environmental sensors. The detection module generates a motion presence signal that indicates whether motion has been detected and that compensates for external environmental factors.

Abstract: An intelligent streetlight may include a modem capable of communicating on a mobile communications network. The intelligent streetlight may be communicate with a network operations center (“NOC”) via the mobile communications network. In some aspects, the intelligent streetlight configures the modem to transmit on the mobile network based on multiple types of network provisioning data. For example, the modem may have a network configuration, such as a low-bandwidth mobile data plan, based on stored provisioning data. The modem may reconfigure the modem based on additional provisioning data for an additional network configuration, such as a high-bandwidth mobile data plan. In some cases, the additional provisioning data is requested by the streetlight from the NOC. In some cases, the NOC may provide the additional provisioning data to multiple intelligent streetlights, such that the multiple streetlights are each reconfigured in a short period of time.

Abstract: A fluid actuator includes housing defining a cylinder bore and first and second fluid passages. A circumferential detent groove extends into the housing from the cylinder bore. The cylinder bore receives a piston having a top face and a skirt in sliding engagement. A circumferential detent ring groove extends radially inwardly into the skirt. The detent ring groove has a first portion of a first depth and a second portion of a second, greater depth. An o-ring is at least partially received in the second portion. A wear ring is at least partially received in the first portion and overlies the o-ring. The o-ring biases the wear ring outwardly of the detent ring so that the wear ring may be selectively engaged with the detent groove.
