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.

A water heating system has a controller that is electronically actuated. In this regard, the controller controls an activation state of at least one heating element by providing an electrical control signal to a relay. In one embodiment, the controller has an emergency shut-off apparatus that is mechanically actuated. Further various features can be optionally implemented to help heat related problems plaguing many conventional water heater controllers that are electronically actuated.

A water heater controller for a water heating system comprises a first temperature sensor, a second temperature sensor, a relay, and logic. The relay an controls an activation state of a heating element. The logic is configured to receive temperature data from the first temperature sensor, and the temperature data is indicative of at least one temperature sensed by the first temperature sensor. The logic is further configured to compensate the temperature data for heat from the relay based on at least one temperature sensed by the second temperature sensor.
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.

The temperature sensor is configured to detect the temperature of the liquid residing within the tank, and the temperature control element is coupled to the tank. The memory stores data indicative of a usage history of the tank, and the logic is configured to automatically control the temperature control element based on the data.
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.
