Abstract: A pool or spa system includes networked pool or spa devices that can be dynamically configured with network addresses by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.

Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.

Abstract: Techniques for NAT-based steering of traffic in cloud-based networks. The techniques may include establishing, by a frontend node of a network, a connection with a client device. The frontend node may receive, via the connection, a packet including an indication of an identity of a service hosted on a backend node of the network. Based at least in part on the indication, the frontend node may establish a second connection with the backend node. Additionally, the frontend node may store a mapping indicating that packets received from the client device are to be sent to the backend node. The techniques may also include receiving another packet at the frontend node or another frontend node of the network. Based at least in part on the mapping, the frontend node or other frontend node may alter one or more network addresses of the other packet and forward it to the backend node.

Abstract: A negative pressure device having a negative pressure source, a canister in fluid communication with the negative pressure source, a conduit the can couple with a wound dressing to provide negative pressure to a space beneath the wound dressing. Some arrangements of the negative pressure source can have a first noise reduction chamber and a second noise reduction chamber downstream of and in fluid communication with an outlet of a pump. The first and second noise reduction chambers can be configured to reduce noise generated by the pump and/or a level of pressure pulses in the fluid that is advanced through the negative pressure source.

Abstract: Techniques and mechanisms to reduce double encryption of packets that are transmitted using encrypted tunnels. The techniques described herein include determining that portions of the packets are already encrypted, identifying portions of the packets that are unencrypted, and selectively encrypting the portions of the packets that are unencrypted prior to transmission through the encrypted tunnel. In this way, potentially private or sensitive data in the packets that is unencrypted, such as information in the packet headers, will be encrypted using the encryption protocol of the encrypted tunnel, but the data of the packets that is already encrypted, such as the payload, may avoid unnecessary double encryption. By reducing (or eliminating) the amount of data in data packets that is double encrypted, the amount of time taken by computing devices, and computing resources consumed, to encrypted traffic for encrypted tunnels may be reduced.

Abstract: Apparatus and methods for non-invasively determining a temperature of a fluid inside a housing are provided. First and second temperature sensors are positioned so that there is a temperature differential between the first and second temperature sensors. A difference between the temperature of the first and second temperature sensors can be used to estimate the temperature of the fluid inside the housing and/or a zero heat flow methodology can be used to determine the temperature of the fluid inside the housing.
