Abstract: An automatic umbilical connector separating mechanism is separable in the same direction as the motion of a flying object. After the two connectors are connected, they are securely held in place by trigger mechanisms to prevent self-loosening and signal loss. When the flying object is launched and slides on the launch rail, the connector frame moves forward, releasing the trigger mechanisms. With tension from the chains and the force from the spring, the male connector frame pulls the male connector in the opposite direction. As a result, the automatic umbilical connector separating mechanism moves in the same direction as the flying object on the pins and guide holes of the connector frames. After the guide pins reach the end of their travel, the spring pulls the male connector frame up the launch pad, while the spring-loaded hinge folds the female connector frame into the flying object body.

Abstract: Systems and methods provide for improving the accuracy of a location system. The location system can capture partial phase vector data from one or more access points (APs). The location system can capture associated data associated with the partial phase vector data across multiple dimensions, such as identity data of the APs and client devices generating the partial phase vector data and frequency band data, location data, a time and date, and other data associated with the partial phase vector data. The location system can determine correlation data across the multiple dimensions using the first partial phase vector data and the associated data. The location system can a cause of the partial phase vector data based on the correlation data. The location system can perform one or more remediation actions based on the cause of the partial phase vector data.

Abstract: An access point includes first and second radios that operate in accordance with first and second wireless protocols, respectively. The access point performs a method including receiving a first protocol packet of the first wireless protocol and a second protocol packet of the second wireless protocol transmitted by a wireless device over a communication channel, and measuring a first received power of the first protocol packet and a second received power of the second protocol packet at the access point. The method further includes determining whether reception times of the first protocol packet and the second protocol packet are within a coherence time for the communication channel and, when the reception times are within the coherence time, combining the first received power and the second received power into a multiprotocol received power. The method also includes determining a location of the wireless device based on the multiprotocol received power.

Abstract: A droplet bandpass filter and method of modifying droplet size distribution of a population of droplets suspended in a gas. Droplets suspended in a gas are flowed through a bandpass filter having a tortuous pathway which comprises at least one impactor region located at a position adjacent to a flow direction change. Larger droplets impact at the impactor region while smaller droplets remain suspended in the gas and flow in the first output direction. Other flow restrictors may advantageously be included in the tortuous pathway. The filter is particularly useful in delivering sterilant aerosols (e.g. peroxides) with reduced populations of large droplets.

Abstract: An enterprise system configures access point devices at an enterprise location to communicate with a location determination system. The location determination system receives wireless signal attributes of user computing devices broadcasting Wi-Fi signal data at the enterprise location from one or more access point devices. For a particular time window, the location determination system determines aggregated features of received wireless signal data across all access point devices, and classifies each of the user computing devices as moving or stationary by applying the wireless signal data to a model. For each of the user computing devices determined to be moving, the location determination system calculates a respective position of the user computing device based on the wireless signal data. For each of the user computing devices determined to be stationary, the location determination system does not calculate a respective position of the respective user computing device.
