Abstract: A crankcase gas separator includes a separator housing delimiting at least part of a separation space and forming at least part of a liquid phase receiving circumferential inner wall surface, a wall member forming at least part of a gas passage, and a gas pressure regulating valve including at least part of the gas passage. The separator includes a separate tube member extending from a position radially inside the inner wall surface into the gas passage. A liquid tight seal between the separate tube member and the wall member is formed by a joint arranged radially outside the inner wall surface.

Abstract: A camera includes a first microphone, a second microphone, one or more drains, and a processor. The processor determines a correlation metric between portions of audio signals obtained from the first and second microphones. The one or more drains drain water away from the first microphone, the second microphone, or both. The camera includes a memory to store the portions of the audio signals as portions of an output audio signal.

Abstract: An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. The audio capture device determines whether one or more microphones are wet or dry and selects one or more audio signals from the one or more microphones depending on their respective conditions. The audio capture device generates a mono audio output signal or a stereo output signal depending on the respective conditions of the one or more microphones.

Abstract: An audio capture device for a submersible camera including a supporting structure to prevent a waterproof membrane from deflecting beyond a point that will cause damage to the membrane. A microphone assembly includes a microphone for detecting ambient sound and generating an electrical signal representing the ambient sound. The microphone assembly is covered by a waterproof membrane to prevent water from reaching the microphone assembly. One or more supporting rings near the waterproof membrane prevents the waterproof membrane from deflecting more than a threshold deflection.

Abstract: It is provided a method for enabling determination of proximity of a mobile device (2a, 2b) to a beacon device (3a). The method is performed by a proximity determiner (1) and comprises the steps of: determining a set of beacon devices (3a-e) being detectable from the mobile device; obtaining beacon measurements of one or two beacon devices in each pair; generating a two-dimensional graph based on the beacon measurements; obtaining device measurements of signal strength of beacons from the beacon devices in the set of beacon devices; finding an optimum in a space defined by the two- dimensional graph; and determining the most probable position of the mobile device in the graph based on the optimum.

Abstract: It is provided a method for enabling determination of proximity of a mobile device (2a, 2b) to a selected proximity determiner (3a). The method comprises the steps of: determining a base set of proximity determiners (3b-e) whereby an enlarged set of proximity determiners is defined as the selected proximity determiner and the base set of proximity determiners; receiving beacon measurements of signal strength of other proximity determiners in the enlarged set of proximity determiners; generating a two-dimensional graph based on the beacon measurements; receiving respective device measurements indicating signal strength of a signal from the mobile device at each proximity determiner in the enlarged set of proximity determiners; finding an optimum in a space defined by the two-dimensional graph; and determining the most probable position of the mobile device in the graph based on the optimum.

Abstract: A camera includes one or more microphone pairs. A first microphone (e.g., a main microphone) is ported to the outside of the camera and captures the desired external audio signal, but may also capture undesired vibrational noise. A second microphone has a similar structure to the first microphone, but is not ported to the outside of the camera. Instead, the second microphone is ported into an enclosed cavity (e.g., 1-2 cubic centimeters in volume). The second microphone may pick up the same vibration excitation and internal acoustic noise as the first microphone but very little of the desired external acoustic sounds around the camera. The unwanted noise can then be removed by subtracting the second audio signal from the second microphone from the main audio signal from the main microphone.

Abstract: A roll for assembling a device (2) for detection and elimination of pest insects includes a wound up, continuous band of fibrous material, the band having a main portion (22) and a first flap folded thereover, wherein at least one aperture (35) is arranged in the main portion along at least part of the length of the continuous band, the face facing away from the first flap such that the adhesive strip completely covers over the at least one aperture, the aperture being at least partially filled with an insecticide in powder form. The roll may include a second flap, wherein the first flap and the second flap at least partially overlap and the second flap is sandwiched between the main portion and the first flap.

Abstract: An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. When the presence of wind noise or other uncorrelated noise is detected, the audio capture device selects, for each of a plurality of different frequency sub-bands, an audio signal having the lowest noise and combines the selected frequency sub-bands signals to generate an output audio signal. When wind noise or other uncorrelated noise is not detected, the audio capture device determines whether each of a plurality of microphones are wet or dry and selects one or more audio signals from the microphones depending on their respective conditions.
