Abstract: Described herein is a waveguide that is configured to be soldered to a printed circuit board (PCB) via one or more metallic portions disposed thereon. Additionally, the waveguide may have solder disposed within thru holes that is configured to conduct heat from one or more components of the PCB when the waveguide is mounted to the PCB. Also described herein is an assembly comprising the waveguide soldered to the PCB via solder between the metallic portions of the waveguide and metallic portions of the PCB. Techniques for producing the waveguide and the assembly are also described herein. By soldering the waveguide to the PCB, an inexpensive, precise, and secure mechanical bonding may be achieved while electrically sealing features of the waveguide and/or components of the PCB. Furthermore, the solder within the thru holes allows for better heat conduction through the waveguide.

Abstract: This document describes techniques, apparatuses, and systems for an antenna-to-printed circuit board (PCB) transition. An apparatus (e.g., a radar system) may include an MMIC or other processor to generate electromagnetic signals. The apparatus can include a PCB that includes multiple layers, a first surface, and a second surface that is opposite and in parallel with the first surface. The PCB can also include a dielectric-filled portion formed between the first surface and second surface. The apparatus can also include a conductive loop located on the first surface and connected to a pair of lines. The apparatus can further include a transition channel mounted on the first surface and positioned over the dielectric-filled portion. The described transition can reduce manufacturing costs and board sizes, reduce energy losses, and support a wide bandwidth.

Abstract: This document describes facia, including parts of vehicles, for supporting an ultra-wide radar field-of-view, for example, in automotive contexts. The facia is configured as a radome for supporting an ultra-wide field-of-view with an antenna despite the facia obstructing a field of view. The facia has one exterior surface or interior surface this is a mostly smooth or has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and increase light transmission through the facia. The other of the exterior or interior surface, has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and further increase light transmission through the facia.

Abstract: On-demand protection and authorization of playback of media assets includes receiving digital media at a server computer, storing intermediary data in a data store, and receiving a request from a client for the digital media. The method also includes generating a protected copy of the digital media from the digital media and the intermediary data. The method also includes storing a description of the protected copy in a database and sending the protected copy to the client. The method also includes receiving a request from the client to access the digital media and reading the description from the database based on information in the request. The method also includes sending a response to the client, the response indicating whether the client is authorized to access the digital media, and the response including cryptographic data to decrypt the protected digital media if the client is authorized to access the digital media.

Abstract: An apparatus, method and combination for dissipating vibration from a head suspension of a data storage device. The combination includes a rotating disc in a data exchange relationship with a read/write head supported by a head suspension formed by the method. The method includes the steps of; forming a mounting region and a load beam region each adjacent a bend region; removing material from the bend region to form an aperture, a strut, an isolation aperture and a damping material support structure; and affixing a damping material to the strut and the damping material support structure. The apparatus includes the bend region adjacent both the mounting region and the load beam region, with the damping material attached to the strut as well as to the damping material support structure. The load beam region includes a rigid portion, which supports a flexure upon which a read/write head is attached.

Abstract: A method for attaching a printed circuit card assembly to an actuator assembly in a disc drive comprises forming one or more pins integrally with the actuator assembly, inserting each pin through a corresponding pin opening in the printed circuit card assembly, and attaching the pins to the printed circuit card assembly. The pins may be attached to the printed circuit card assembly by a soldering process, or alternatively, pressure may be applied to a top surface of the pins to cause them to deform over the printed circuit card assembly, thereby securing the printed circuit card assembly to the actuator assembly. A disc drive in accordance with a preferred embodiment of this invention has an actuator assembly with one or more integral pins and a printed circuit card assembly attached to the integral pins.

Downstream processing circuitry is coupled to the high-pass filter, and upstream processing circuitry is selectively coupled to the first low-pass filter and the second low-pass filter in response to an indicium of a desired spectral region.

Abstract: An actuator assembly for use in a data storage device is described that has features that reduce off-track writes due to coil popping. The fantail portion of the actuator includes thermal restraint features that engage with the over-mold, and the thermal restraint feature are positioned prevent the over-mold from separating from the actuator as a result of the over-mold and the actuator having different coefficients of thermal expansion. The thermal restraint features reduce the length of effective interface between the actuator and the over-mold acted upon by shear forces due to coefficient of thermal expansion mismatch. In one example, the thermal restraint features are holes that extend through the actuator, to allow the over-mold to flow through the holes and connect on both sides of the fantail during molding, effectively interlocking the fantail portion to the over-mold.

Abstract: The present invention is an apparatus and method for an improved actuator arm assembly in a disc drive. This invention results from the realization that structurally inferior actuator assemblies create low frequency, high amplitude resonances. This invention reduces resonances through the utilization of a voice coil motor overmolding technique that additionally incorporates a stiffening member to increase the rigidity of the actuator assembly.

Abstract: A signal interface supports bi-directional communication in a signal communication system. The signal interface is preferably utilized within a cable television/communication system set top box. The signal interface includes a diplexer positioned between an input/output of the set top box and a signal splitter. By positioning the diplexer before the signal splitter, there is no attenuation of a return data channel (RDC) signal. Thus, a lower gain RDC amplifier may be used. Additionally, the signal splitter is operable over a smaller frequency range since the signal splitter need only operate over the frequency bandwidth of the video signal and not the combined frequency bandwidth of the video signal and the RDC.

Abstract: A resilient linear latch and crash stop device incorporates a magnetic latch and a linear impact absorbing crash stop into a single composite body made up of a magnet member for contacting a strike plate on the actuator arm, an energy absorbing member, and a latch base body assembled together. The energy absorbing member fastens the magnet member to the base body and absorbs impact energy in a generally linear fashion throughout the range of anticipated impact magnitudes. The energy absorbing member is a generally rectangular elastomeric bellows member formed in place and sandwiched between the magnetic mounting plate and the base body. The elastomeric bellows member has a vertically open tubular passage therethrough that preferably has a bell shaped horizontal cross sectional shape.
