An eye test administered to a remote subject over a computer network, where sensors provide feedback through the computer network so that light source position, light source brightness and/or a display configuration and/or parameter setting related to a visual display that is used to implement the remote eye test.

A machine can be accessed and controlled with the help of an interface device. The customizable interface device contains device elements that define features relating to the external representation and internal functionality of the interface device, as linked to one or more machines. An operator can use a configuration station to implement single or reoccurring queries that interact with the interface device and corresponding machines. In particular, the queries target the configuration of device elements in the interface device. The process can include temporarily unloading unused features from active memory and mirroring property changes initialized by a source. An emulator can assist in the configuration process by providing a preliminary software representation of the interface device hardware. A user can develop, test, and reconfigure functions on the emulator before loading the finalized platform to the interface device.

A manufacturing device monitoring system includes a plurality of manufacturing devices and a remote monitoring device. The manufacturing device includes a work unit, an equipment notifier, an error detector, and an error notifier. The error notifier determines whether or not an error detected by the error detector may be corrected by an operation from the remote monitoring device, notifies the remote monitoring device of the occurrence of the error in a case where the error can be corrected, and operates the equipment notifier to notify a first notification pattern in a case where the error cannot be corrected.

An apparatus, system, and methods for measuring environmental parameters are disclosed. The apparatus, system and methods can be used for a variety of applications, including HVAC air balancing and building commissioning. The system includes a variety of wireless sensing modules and wearable modules for control. display, and storage. Parameters measured include air and water temperature, pressure. velocity, and flow. Also included are sensors for light intensity, CO concentrations, and CO2 concentrations.

An Animal Feed Mixer (Dairy or Beef) Scale indicator system records Feed Mixer Operating Speed along with the operating temperatures and hydraulic & lube oil pressures of the mixer gearboxes and hydraulic drive system and notifies the operator and records the temperature or pressures, along with the weight, date, and time, when limits have been exceeded.

Implementations of an airflow capture hood flow control ring may include a flexible ring including a toroidal shape configured to couple around a base of an airflow capture hood. The ring may be configured to permit an airflow sensor coupled to the airflow capture hood coupled to an inlet to measure a flow of air into the inlet with at least 90% accuracy.

A method includes the step of receiving a first weight value from a sensor associated with a feed mixer. A first rotation speed associated with the first weight value is monitored. A second weight value is received from the sensor associated with the feed mixer and a second rotation speed associated with the second weight value is monitored. A mixing profile is generated based on the first weight value, the second weight value, the first rotation speed, and the second rotation speed. In one embodiment, a first feed ingredient is associated with the first weight value and a second feed ingredient is associated with the second weight value.
