Abstract: One example may include a method that includes initiating an audio recording to capture audio data, comparing the audio data received from a microphone of a mobile device to an audio data range, determining whether the audio data is above an optimal level based on a result of the comparison, and queuing the audio data in an audio data queue when the audio data is above the optimal level.

Abstract: Techniques for network latency estimation in a computer network are disclosed herein. One example technique includes instructing first and second nodes in the computer network to individually perform traceroute operations along a first round-trip route and a second round-trip route between the first and second nodes. The first round-trip route includes an inbound network path of an existing round-trip route between the first and second nodes and an outbound network path that is a reverse of the inbound network path. The second round-trip route has an outbound network path of the existing round-trip route and an inbound network path that is a reverse of the outbound network path. The example technique further includes upon receiving traceroute information from the additional traceroute operations, determine a latency difference between the inbound and outbound network paths of the existing round-trip route based on the received additional traceroute information.

Abstract: The disclosure provides for a device for selectively agitating briquettes on a grill supporting plate. The device includes a variable frequency vibrational device, a power source, and a control circuit that controls the vibrational device at selected frequencies to create various Chladni patterns in the plate and, therefore, heating patterns over the surface of a briquette-supporting pan. The plate supports one or more pieces of charcoal and the device is integrated into the pan. When turned on, the vibrational device vibrates at a selected frequency. This vibration is translated to the briquette-supporting plate and causes different charcoal briquettes to selectively vibrate. The device is capable of selectively activating or pixilating briquettes to generate higher temperatures over different surface areas of the plate when the grill is cooking one or more pieces of food requiring different degrees of grilling or cooking.

Abstract: A system includes a flexible datacenter and an energy storage unit that receives and stores power from one or more grid-scale power generation units. The energy storage unit and the flexible datacenter are connected behind-the-meter to the power generation unit(s) such that they are not typically subject to grid transmission and distribution fees. By various methods, behind-the-meter power is routed between the power generation unit(s), the energy storage unit, the flexible datacenter, and/or the grid based on a variety of conditions and operational directives.

Abstract: A protected substrate includes a planar substrate having a surface and a burn-off temporary protective layer positioned over at least a portion of the surface. The burn-off temporary protective layer includes a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof. The burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface. Various other protected substrates and methods for protecting a substrate are also disclosed.

Abstract: Disclosed is a bi-directional exhalation valve useful for many applications such as in CPAP devices. The exhalation valve includes a valve body having a center chamber, side chambers, and bidirectional ports coupled to the center chamber via passages and a mechanism that provides fluid ingress into the bi-directional valve in a first mode of operation or fluid egress from the bi-directional valve in a second mode of operation. Unidirectional ports are coupled to the plurality of bidirectional ports to provide providing fluid egress from the valve in the second mode of operation, and a unidirectional port provides fluid ingress into the bi-directional valve in the first mode of operation. A mechanism including a center paddle, side paddles, and a shaft are arranged in an elongated compartment of the valve body, such that the shaft is pivots and the central and side paddles open and close corresponding ones of the input and output ports.

Abstract: A battery system includes a plurality of battery cells connected in parallel. Each battery cell includes a positive and negative tab. The battery system also includes a plurality of thermal switch devices (e.g., temperature cut off (TCO) or positive temperature coefficient (PTC) devices). Each thermal switch device is electrically coupled to a respective cell. The battery system further includes a rigid-flex circuit board comprising a plurality of rigid regions. Each rigid region is physically and electrically connected to an adjacent rigid region by a respective flexible region. Each rigid region is electrically coupled to respective positive and negative tabs of a respective battery cell. Each thermal switch device prevents abnormal current flow (e.g., by limiting the flow of current at high temperatures) between a first battery cell that is coupled to the thermal switch device and a second battery cell that is adjacent to the first battery cell.

Abstract: An edge lit fixture. A light engine comprises a compartment and at least one elongated lens that are attachable to a mount plate. The mount plate, an exterior surface of the compartment, and the lens define an internal optical cavity. A light strip is mounted to the mount plate within the optical cavity. One or more legs can be used to attach the fixture to an external surface, such as a ceiling T-grid. The light engine can be used with legs of varying size such that it can fit within ceiling openings having different dimensions. The assembled fixture defines an open area. One or more light engines are arranged around or through the open area such that light is emitted into the open area. The open area of the fixture allows for existing materials, such as a ceiling tile, for example, to function as a back side reflector panel.

Abstract: The present disclosure relates to a system for controlling ignition of an air/fuel mixture intake charge directed into an internal combustion engine. The system may have a longitudinally movable inner cylinder liner configured to fit within a cylinder wall portion of an internal combustion engine, and able to receive a piston of the engine therein. A portion of the inner cylinder liner defines an internal volume forming a combustion chamber, and the internal volume controls a compression ratio of the cylinder. The system also has a cylinder head assembly operatively associated with the inner cylinder liner and able to move linearly to cause longitudinal displacement of the inner cylinder liner relative to the cylinder wall portion. This enables the volume of the combustion chamber to be further varied, to thus further vary the compression ratio.

Abstract: Methods and apparatus for providing quasi-licensed intra-cell spectrum reassignment. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a “seamless” reassignment of wireless spectrum without disruption or loss of continuity to existing data sessions of the CBSD is provided via a pool of temporary RF carriers which act as substitutes for the currently allocated (granted) carriers. The served user devices (e.g., UEs) are instructed by the CBSD to migrate to a new “final” carrier via the substitutes, either directly or via one or more intermediary hops. In one variant, existing 3GPP signaling mechanisms between the UE and CBSD/eNodeB obviates any changes to extant UEs. Communications between the CBSD and its cognizant SAS/DP include new information objects which direct the CBSD to implement the handover functionality. In a further variant, inter-CBSD sector and frequency handovers are provided for using CBRS-plane and 3GPP signaling.
