摘要:
A tractor unit (10) and a trailer unit (14) are connected by a connecting pin (33) on one unit (12, 14) which is in use received in an opening (21) in a connecting surface of the other unit, the connecting pin (33) including a sensor device (70) to sense loads imposed on the connecting pin (33) as the trailer unit (14) tends to decelerate or accelerate relative to the tractor unit (12), there being a control system, including a controller (65) which receives signals from the sensor device (70) representative of loads imposed on the connecting pin (33), and at least one electrical motive machine (50) is controlled, the machine (50) being capable of being electrically driven by power from an electrical storage device to provide drive to drive at least one ground engaging wheel (45a, 45b) and of generating electrical power for storage by an electrical storage device (58), such as to minimize the loads imposed on the connecting pin (33).

An electronic device may be provided with a housing. A camera module may be mounted within the housing. The housing may have a camera window with which a lens in the camera module is aligned. To rotationally and laterally align the camera module with respect to the camera window and the electronic device housing, an alignment structure may be mounted to the housing in alignment with the camera window and housing. The alignment structure may be formed form a ring-shaped structure with an opening. The alignment structures may have sidewalls that form an alignment groove for the camera module. The camera window may be formed from a circular opening in a layer of opaque material deposited on a transparent housing member such as a planar layer of glass. During the process, a laser tool may be used to trim the opening in the opaque material.

To prevent debris from entering the volume between a dome and contacts of a dome switch, a dome can include a channel providing a remote path through which air can be vented. In particular, the channel can extend from the dome to a location within an electronic device that is known to be or expected to be contaminant free (e.g., a region of the device that does not include any interfaces communicating with the device environment). The channel can be defined from components of the dome switch including, for example, as a channel bound by spacer walls between a flex circuit and a film layer. The channel can include an opening for venting the dome switch. In some embodiments, the dome switch can include a protective film applied over the opening in the channel. The protective film can be selected to allow air to flow through, but to prevent contaminants or particles from reaching the channel opening.

An electronic device can include different components providing different functionality. Some electronic devices can include a proximity sensor for determining when a user's face is near the device. The sensor can include an emitter and a detector that are separated by a foam block to limit cross-talk between the emitter and detector. A sheet can be placed over the foam block to define openings for each of the emitter and detector. Some electronic devices can also include a camera. A glass cover secured to the device enclosure can protect the camera. To improve an adhesive bond between the glass cover and a metal enclosure, an ink layer can be placed between an adhesive and the glass. In addition, the camera or another component may need to be grounded to ensure proper operation. During assembly, however, the position of the camera can shift due to closing an enclosure. A grounding assembly that maintains contact with the camera in its initial and final positions can be provided.

Methods for non-invasive prenatal ploidy calling are disclosed herein. Methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a sample of DNA from the mother of the fetus and from the fetus, and from genotypic data from the mother and optionally also from the father are disclosed herein. The ploidy state is determined by using a joint distribution model to create a set of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. In an embodiment, the mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias.

Components may be interconnected using liquid materials such as liquid adhesive and solder. To prevent undesired movement between the components during the assembly process and to prevent the liquid material from flowing into undesired areas, an attachment and dam structure may be provided. The structure may be formed from a substrate such as a flexible polymer film coated with adhesive. When interposed between first and second components, the structure attaches the first and second components and prevents movement between the first and second components. The structure may have one or more edges adjacent to the liquid material to block the liquid material from flowing while the liquid material is in its liquid state. Once the components have been connected, the liquid material can be solidified.

摘要:
Apparatus for supporting a disk drive with a rotating disk about a disk axis and an arm which pivots over the disk about an arm axis. The disk axis and the arm axis are perpendicular to the plane of the disk. The apparatus includes a disk drive carrier having a disk drive receiving portion where disk drive can be received, and a housing in which the carrier can be received. A mounting arrangement is provided for supporting the carrier within the housing such that the center of rotation of the carrier is outside the disk drive receiving portion of the carrier. Additionally, a mounting arrangement is provided for supporting the carrier within the housing, comprising a forced pivot at or towards the opposite end of the disk drive carrier, and about which the carrier is fixed for pivotal movement in the housing.
