Apparatus and methods to reduce unwanted motion in precision instruments are described. An active vibration-isolation system may include a feedback loop that senses motion of an intermediate mass. In noisy environments, where the feedback loop would otherwise fail or provide inadequate isolation, feedforward control can be implemented to sense floor vibrations and reduce motion of the intermediate mass that would otherwise be induced by the floor vibrations. The feedforward control can reduce motion of the intermediate mass to a level that allows the feedback loop to operate satisfactorily.

A tank including a fluid reservoir, a communication module, a controller, and at least one sensor. The fluid reservoir is configured to be in fluid communication with a cable segment. The communication module is configured to communicate with an external device. The sensor is configured to detect an injection parameter value, encode the injection parameter value in a sensor signal, and send the sensor signal to the controller. The controller is configured to automatically instruct the communication module to transmit information to the external device based on the injection parameter value.

Disclosed herein are systems, apparatuses, methods, and non-transitory computer readable media related to a display construct coupled to a structure (e.g., a vision window). The structure can be a supportive structure such as a fixture. The display construct is configured to facilitate media display and is at least partially transparent. The vision window may be a tintable window, e.g., a window in which its tint is electrically controllable (e.g., an electrochromic window). Various interactive capabilities with the display construct are disclosed (e.g., via a touch screen).

A device may monitor an intake temperature of an air flow through an air intake of a building that includes a ventilation system for temperature control of a first region of the building, a liquid cooling system for temperature control of equipment that is within a second region of the building, and a heat exchanger that is thermally coupled to the ventilation system and the liquid cooling system. The device may determine that the intake temperature is below a threshold temperature. The device may control the ventilation system to cause the air flow to cool a water flow of the liquid cooling system via the heat exchanger to produce a cooled water flow. The device may control the liquid cooling system to cause the cooled water flow of the liquid cooling system to bypass a chiller system of the liquid cooling system to reduce power consumption by the chiller system.

Disclosed herein are various clusters. A cluster comprises processing nodes that have supervisory roles and subordinate roles. A node in the cluster can have a supervisory or a subordinate role. The cluster can self-orchestrate its roles. The roles of the nodes can be assigned and/or reassigned (e.g., autonomously and/or automatically) by the cluster. Such system may achieve automatic commissioning of the cluster(s), e.g., in a facility.

Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to reduction and/or identification of one or more health risks in a facility. For example, by sensing a bodily characteristic of an individual in a facility, e.g., by sensing at least one environmental characteristic. For example, by sensing surface cleanliness. For example, by tracking personnel in the facility. For example, by suggesting routes in an enclosure based at least in part in personnel concentration in the facility. Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to monitoring occupancy of a facility.

A package scanning conveyance system that integrates a first two-dimensional image with at least a second two-dimensional image or a three-dimensional point clouds to calculate or estimate a package's physical properties, and/or determine if there are two or more packages in a pile. The captured imaging data is transformed by the inventive system to provide real-time feedback to a human operator to enable the operator to maintain an understanding of the system's performance. The imaging data may also be used to perform quality-checks on other parts of the package delivery and conveyance systems and document the condition of packages that have passed through the system.

The present disclosure pertains to systems and methods to compress an input signal representing a parameter in an electric power system. In one embodiment, a system includes a data acquisition subsystem to receive an input signal comprising a plurality of high-speed representations of electrical conditions. A linear prediction subsystem generates an excitation signal estimate based on the input signal, a plurality of linear prediction coefficients based on the input signal, and an estimated signal based on the excitation signal estimate and the plurality of linear prediction coefficients. An error encoding subsystem may generate an encoding of an error signal based on a difference between the input signal and the estimated signal. A non-transitory computer-readable storage medium may store an encoded and compressed representation of the input signal comprising the excitation signal estimate, the plurality of linear prediction coefficients, and the encoding of the error signal.
