Abstract: The resolution and contrast of impedance measurements and scans are improved by using a non-contact impedance probe comprising an inner conductor configured to bear a measurement signal and an outer conductor configured to bear a shielding signal. The measurement signal and shielding signal are selected to increase the directionality of the flux emitted from the impedance probe. In one embodiment, the measurement signal and the shielding signal are phase locked signals. A sample may be placed in a basin having a conductive surface that receives the flux emitted from the impedance probe. By filling the basin with a conductive solution, direct contact between the probe and the sample may be avoided along with the associated variability in contact resistance. The small highly-directional flux emitting area achievable with the present invention enables high resolution high contrast non-contact scanning of biological and non-biological materials.

Abstract: A thermal protection device shaped and sized to substantially cover a child car seat is placed within an interior portion of the child car seat to form an air pocket and thereby thermally protect the child car seat. In one embodiment, the thermal protection device includes a thermal barrier, and a positioning strap. The thermal barrier includes a reflecting layer configured to reflect radiant energy, an insulating layer configured to provide thermal resistance, and in one embodiment, an absorbing layer configured to absorb radiant energy. In one embodiment, a pouch configured to detachably connect to the flexible washable thermal barrier contains a temperature moderation device. The pouch is preferably located within the air pocket at a location that facilitates temperature moderation of the interior portion of the child car seat particularly those components that may contact an occupant.
Abstract: An irrigation controller with an embedded web server activates irrigation devices in accordance with an event schedule. The event schedule maybe accessed and modified via a browser-equipped client. In certain embodiments, watering rates and schedules are adjusted in response to sensor inputs. The controller may query specialized network servers such as time servers or weather servers to update the controller clock and/or modify the event schedule. The controller may support multiple protocols such as email, FTP, UDP, HTTP and the like. The controller may be configured as a master or slave controller such that multiple slave controllers may coordinate with a master controller and modify their event schedules in accordance with the master event schedule. The result is an irrigation controller that is easily configured, locally or remotely accessible, responsive to varying weather conditions, and suitable for complex multi zone, multi-system configurations.
Abstract: A selectively cascadeable storage unit allows a variable number of containers to be stored and dispensed in a first-in, first-out manner. The storage unit includes a receiving area, a storage track, a dispensing area, and a selectively engageable stop. The storage track conveys containers from the receiving area to the dispensing area, where the selectively engageable stop either holds the containers or passes the containers to a cascaded storage unit. In one embodiment, multiple storage units are substantially overlapped such that containers may be selectively passed from the dispensing area of one unit to the receiving area of the connected unit. The present invention facilitates better utilization of storage facilities and simplifies inventory management of a variety of containers such as barrels, bottles, boxes, cans, cartons, casks, crates, drums, jars, kegs, packages, sacks, tins, and tubs.
