摘要:
A sensor for determining soil properties is disclosed herein. The sensor includes a ground engaging structure adapted for coupling to an agricultural implement and to penetrate soil at a predetermined depth. An electrode assembly is disposed on a sensing surface of the ground engaging structure that includes a plurality of electrode sensing units. The plurality of electrode sensing units are configured to selectively, being separately activated by a switching circuit, generate a series of electric fields that project outwardly into the surrounding soil in response to receipt of an excitation signal and sense changes in the electric field corresponding to a change in a measured electrical output signal that is used to determine one or more soil properties during movement of the agricultural implement in a field.

摘要:
An illustrative humidity sensor may include a substrate having a source and a drain, wherein the drain is laterally spaced from the source. A gate stack is provided in the space between the source and the drain to form a transistor. The gate stack may include a gate insulator situated on the substrate to form a gate insulator/substrate interface. The gate stack may further include a barrier layer above the gate insulator. The barrier layer may be configured to act as a barrier to mobile charge, humidity and/or other contaminates, and may help prevent such contaminates from reaching the gate insulator/substrate interface. The gate stack may further include a humidity sensing layer above the barrier layer. The humidity sensing layer, when exposed to humidity, may modulate the conduction channel in the substrate under the gate insulator and between the source and the drain. In some cases, the humidity level may be determined by monitoring the current flowing between the source and drain.

摘要:
In a sample analyzing apparatus, an injector assembly injects a reagent onto a sample, and luminescent light from the sample is transmitted to a detector. The assembly may be movable toward and away from the sample. The assembly may include one or more needles that communicate with one or more reservoirs supplying reagent or other liquids. The assembly may include a light guide for communicating with the detector. A cartridge may be provided in which the assembly, one or more reservoirs, and one or more pumps are disposed. The cartridge and/or the apparatus may be configured for enabling rinsing or priming to be done outside the apparatus. The cartridge and/or the apparatus may include one or more types of sensors configured for detecting, for example, the presence of liquid or bubbles in one or more locations of the apparatus and/or the cartridge.
