A sensor assembly is disclosed. The sensor assembly includes a housing that includes a top housing and a bottom housing that clamp together. The sensor assembly also includes a printed circuit board assembly (PBA). The sensor assembly also includes at least one piece of elastic material that is located in between the top housing and the PBA and in between the bottom housing and the PBA. When the PBA is clamped in the housing, the sensor assembly allows the PBA to maintain alignment relative to the housing across different environments in order to enable proper operation of the sensor assembly. A top surface of the PBA and a bottom surface of the PBA each have at least one three-dimensional feature that is designed to increase friction with the elastic material.

Isolating sensor assembly using elastic material

A shock mount assembly for a sensor protector apparatus is provided. The shock mount assembly comprises a support structure having a geometric configuration, with the support structure including at least one side wall having an outer edge section that defines a periphery of the support structure, and at least one mounting surface substantially perpendicular to the side wall. The mounting surface is configured for coupling at least one electronic device to the support structure. A shock absorber is mounted to at least a portion of the outer edge section, with the shock absorber substantially surrounding the periphery of the support structure. The shock mount assembly is configured for a non-isolated system, and is configured to protect the electronic device during vibration or shock events.

Shock mount in environment sensor protector for non-isolated systems

Systems and methods for potted shock isolation are provided. In once embodiment a shock isolation system comprises an isolator comprising an outer ring for mounting to an external housing, and an inner ring connected to the outer ring via an isolating element; and an inertial sensing assembly comprising: at least one circuit board secured to the inner ring of the isolator, the at least one circuit board further comprising a triad of gyroscopes and a triad of accelerometers; and a low durometer highly dampened supporting material encapsulating a first surface of the at least one circuit board.

Systems and methods for potted shock isolation

Systems and methods for providing vibration isolation for a MEMS device are provided. In at least one embodiment, a system comprises a first assembly and a second assembly, wherein the second assembly and the first assembly are joined together, enclosing the MEMS device, wherein the joined first assembly and the second assembly have a recessed groove formed on an interior surface. Further, the system comprises a rigid support encircling the MEMS device, the rigid support fitting within the recessed groove; and at least one mount isolator in contact with a plurality of surfaces of the rigid support, wherein the at least one mount isolator interfaces the plurality of surfaces of the rigid support with the first assembly and the second assembly, when the first assembly and the second assembly are joined together.

Systems and methods for high frequency isolation

A three-dimensional PWB is provided that may include two or more layers stacked together forming a top surface, a bottom surface, and one or more side surfaces, and one or more solder pad situated on at least one of the one or more side surfaces. The one or more solder pads may include exposed voids in the one or more side surfaces. In some cases, the top surface and/or the bottom surface may have one or more solder pad. The one or more solder pads on at least one of the one or more side surfaces may be electrically connected to the one or more solder pads on the top surface and/or the bottom surface. In the illustrative PWB, the top surface and/or the bottom surface may be adapted to be mounted with an inertial sensor. The one or more side surfaces may be adapted to be mounted to a printed wiring board.

Three-dimensional printed circuit board

A packaging assembly includes a printed circuit assembly coupled to a stiffening device, which may take the form of a custom-shaped stiffening member or take the form of a support member having spokes attached to a rim. The printed circuit assembly includes a printed circuit board with a number of electrical components extending from a surface of the board. The stiffening member or the support member includes openings that receive the electrical components while providing additional stiffness to the board.

Stiffening support for printed circuit assemblies

An inertial measurement unit (IMU) is provided that includes a container that defines a cavity. A sensor suit or ISA having a housing is provided in the container of the IMU. A dampening material is provided between the housing of the ISA and the container of the IMU. The dampening material may be applied by coating, spraying, or dipping, or may be separately molded and then inserted, if desired. A sway space may also be provided between the ISA and the IMU container.

Gunhard shock isolation system

Disclosed is a compact vibration isolation system for mounting an inertial sensor assembly (ISA) to an Inertial Measurement Unit (IMU) housing. The housing is mounted to a support that is subjected to shock and vibration. The vibration isolator assembly includes a ring shaped elastomeric member laminated between a ring shaped inner member and a ring shaped outer member. The inner member is securely mounted to the ISA, and the outer member is mounted to a support of the IMU housing. Because of the compact size of this system, the IMU housing contains and protects the elastomeric member from potential contamination and damage, as well as eliminates the need for delicate mechanical and electrical interfaces. The elastomeric member of the system isolates the ISA from shock, vibration, and acoustic energy that may otherwise be transmitted from the support to the ISA.
