Abstract: An airbox for an air intake system of an engine includes an air inlet for receiving air into the airbox, an air outlet for discharging air from the airbox, and an airbox body defining first and second expansion chambers fluidly connected to one another. The airbox body has a dividing wall separating the first expansion chamber from the second expansion chamber, the dividing wall defining a wall opening fluidly connecting the first and second expansion chambers. An interchangeable flute is removably connected to the airbox body. The interchangeable flute is at least partly disposed in the second expansion chamber and positioned to guide air flowing into the air inlet into the second expansion chamber. The interchangeable flute is removable such that a replacement flute can be installed in its place to selectively modify a noise output of the airbox. Other aspects are also contemplated.

Abstract: Disclosed is a technique for passively monitoring the number of guests in a rental property. Mobile device broadcasts intended for connecting the device to a wireless network contain information about that device. This information includes unique identifiers such as MAC addresses. Detecting these broadcasts and filtering out those devices that are expected enables a property owner to have a semi-accurate number of guests within their property without actually being at the property, or visibly observing the guests in an obtrusive fashion. Guests are able to enjoy themselves in privacy and the property owner is able to monitor the safety of their property.

Abstract: Disclosed herein is a technique to improve the processing of people counting systems. The technique involves the use of a system that counts the local number of wireless/mobile devices via machine identifiers. When the counting device scrapes the machine identifier from a mobile device, the identifier is hashed using a one-way hash function. The hash code corresponds to a bit location on a bitmap. The location in the bitmap is checked. If the bit is already marked full, the mobile device has been previously detected, if the pixel location is empty, this is a new device. Thus, a single bit represents each machine identifier. The number of unique people in a monitored location is the number of full bits in the bitmap.

Abstract: Disclosed herein is a technique to mask personally identifying information (PII) in a people counting system. A sensor that capable of identifying individual mobile devices, such as smart phones, counts people in a given area. Once identified, information that identifies given mobile devices is hashed. The hashed data is used with a filter to determine recurrence of individuals without actually storing any information specifically about those individuals. In order to determine the count of people externally from the sensor, the hashed data is analyzed for cardinality.

Abstract: A submersible robot for operating a tool relative to a surface of an underwater structure has a tool holder movably mounted on a support assembly provided with a driving arrangement for movably holding the tool in operative position relative to the surface. Position and orientation of the support assembly relative to the surface is locked and adjusted by locking and leveling arrangements. A programmable control unit operates the driving, locking and leveling arrangements and the tool and receives measurements from a sensor unit. The control unit has an operation mode wherein a positioning of the robot is determined and controlled as function of an initial position for defining a first work area, and shifted positions of the robot for defining additional work areas, the work areas having overlapping portions with one another for tracking displacements of the robot relative to the surface of the structure using the sensor unit.

Abstract: A hub 1 integral with the injection pump to include a housing 2 driven in rotation, surrounding hub 1 and including two rollers 4, 5 placed parallel to the axis of the housing at a distance from this axis. An eccentric governor weight 15 is mounted on hub 1 to be able to move in one direction under the action of the centrifugal force. Two advance control pistons 8, 9 with axis orthogonal to the axes of the hub are mounted in the hub, each to be able to slide in a recessed bore and each equipped with a lateral support ramp 10, 11 able to work with one of the rollers 4, 5 to cause an angular offset between hub 1 and housing 2. One of the pistons 8 acts in the other direction on governor weight 15 by a spring 18. A hydraulic circuit goes through the hub and has a distributor with controlled relief 20 adjusting the pressure acting on pistons 8, 9 as a function of the position of governor weight 15.

Abstract: A hydraulic automatic device for the injection advance of a diesel engine. The device includes a hub fixed to the pump camshaft and a casing fixed to the drive pinion of the pump. Two rollers in the casing bear on the ramps of the pistons of which the position is a function of the speed of rotation, owing to two inertia blocks, the thrust of the pistons and the control of the slide valve of a hydraulic distributor. Thus at each speed of rotation, there corresponds a certain angular displacement of the components and a certain advance of the injections.
