摘要:
Embodiments of the present disclosure generally pertain to systems and methods for estimating and indicating temperature characteristics of temperature controlled liquids. A system in accordance with one exemplary embodiment of the present disclosure has a tank filled at least partially with a liquid, such as water, and the system has a plurality of temperature sensors mounted on the tank. During operation, a controller compares temperatures sensed by these temperature sensors to a predefined temperature profile for the liquid within the tank in order to estimate the likely temperature characteristics of such liquid. The controller then reports these estimated temperature characteristics via a user interface. As an example, the controller may estimate and report the amount of liquid above a threshold temperature that can be drawn from the tank. Based on the reported temperature characteristics, a user may make decisions about whether or how to use liquid drawn from the tank.

摘要:
Described are microfluidic devices for, preferably, high-throughput, multi-analyte, affinity capture and detection of affinity-bindable analytes in biological fluids. Particularly, the devices can be used for immunoassays of biological fluids using multiple antibodies for capture and detection of multiple analytes, including proteins. The devices can be used for the simultaneous isolation and quantization of multiple proteins from microliter samples of biological fluids. Also described are methods for detecting and, optionally, quantifying, affinity-bindable analytes in biological fluids using these devices.
摘要:
A battery health monitor (BHM) that operates as a battery-mountable full-spectrum alternating current (ac) impedance meter that facilitates monitoring a state-of-charge and a state-of-health of a battery. The BHM is used for monitoring one or more electrical parameters, e.g., impedance, of a battery. The BHM includes: a current sink coupled to the first terminal and configured to sink therefrom an oscillatory current so as to cause the battery to produce at a first terminal thereof an oscillatory voltage equal to or less than a dc operating voltage of the battery that would be present at the first terminal in the absence of the oscillatory current; and a voltage sensor configured to sense the oscillatory voltage at the first terminal.

A water heating system has a tank, a first heating element, a first temperature sensor, and a controller. The first heating element is mounted on the tank, and the controller is electrically coupled to the first temperature sensor. The controller is configured to detect a stacking condition based on the first temperature sensor and to disable the first heating element in response to detection of the stacking condition.
摘要:
A controller for a water heating system has an electrical interface, a housing, and logic. The electrical interface receives an electrically conductive wire that is covered by a coating composed of electrically insulating material. An exposed end of the wire is inserted into the electrical interface. The housing has a hole through which the wire passes. The electrical interface and a wall of the housing are separated by a gap so that the coating can pass through the hole and reside in the gap without passing into the electrical interface. The logic is configured to control an operational state of a heating element.
