Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

A folded lens system may include multiple lenses with refractive power and a light path folding element. Light entering the camera through lens(es) on a first optical path or axis is refracted to the folding element, which changes direction of the light onto a second optical path or axis with lens(es) that refract the light to form an image plane at a photosensor. At least one of the object side and image side surfaces of at least one of the lens elements may be aspheric. Total track length (TTL) of the lens system may be 16.0 mm or less. The lens system may be configured so that the telephoto ration |TTL/f| is greater than 1.0. Materials, radii of curvature, shapes, sizes, spacing, and aspheric coefficients of the optical elements may be selected to achieve quality optical performance and high image resolution in a small form factor camera.

An SFP module includes a housing (1) and an ejector (70). An ejector seat (111) is formed in the housing for receiving the ejector. A triangular latch (114) is formed on the housing behind the ejector seat. The ejector includes a push bar (79) exposed forward of a front end (17) of the housing, and a tongue board (74).

Certain aspects of a method and system for providing wireless communication may include a single integrated circuit (IC) that handles communication for at least a Bluetooth (BT) connection and a Wireless Local Area Network (WLAN) connection by controlling transmission of acknowledgement signals based on a measured voice quality for one or both of the BT connection and the WLAN connection. The transmission of the acknowledgement signals communicated from the mobile station to an access point may be controlled. A BT priority signal may be asserted if data to be transmitted comprises high quality voice (HV3) data. The transmission of the acknowledgement signals may be controlled by raising a priority of an asserted WLAN priority signal higher than a priority of the asserted BT priority signal. The voice data may be transmitted via high quality voice (HV3) frames over the BT connection based on the asserted WLAN priority signal.

Techniques for improving electrical performance of a connector. The techniques are compatible with the form factor of a standardized connector, such as an SFP connector or stacked SFP. The resulting connector has reduced insertion loss for high speed signals. Such techniques, which can be used separately or together, include shaping of conductive elements within the connector while still retaining the same mating contact arrangement. Changes may be made at the contact tail portions or in the intermediate portions where engagement to a connector housing occurs. The techniques also include the incorporation of lossy bridging members between conductive elements designated to be ground conductors. For connectors according to the stacked SFP configuration, multiple bridging members may be incorporated at multiple locations within the connector.

A small form-factor transceiver module performs protocol translation, in addition to the conventional electrical and/or optical transmission media conversion. Such protocol conversion may enable transport of traffic from limited-range primary networks over long-range secondary networks, such as extension of Ethernet networks over low-rate TDM links. Additionally, such protocol conversion may enable interworking between different networks of differing technologies, such as transport of ATM traffic over Ethernet networks. The transceiver module may be a Small Form Factor transceiver (SFF), Small Form Factor pluggable module (SFP), Gigabit Interface Converter (GBIC) or any similar small form-factor module consisting of a housing, internal electronic circuitry and optionally optical components, and associated electrical or optical connectors. The transceiver module performs protocol translation by means of an integral protocol translation unit that performs standards-based or proprietary conversion between network protocols.

A virtual memory manager is implemented in optimized, hardwired logic. The virtual memory manager allows the use of a virtual number of network connections which is limited only by the amount of internal and external memory available.

An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension. Each tier is a 1U modular computer system having a computer chassis configured for mounting in the multi-tiered support, and computer components that need cooling within the computer chassis. A cold plate is in thermal communication with at least one of the computer components, and convectively removes heat from that component using a liquid coolant. A heat exchanger dissipates heat from the liquid coolant, and provides liquid coolant back to the cold plate. An air mover within the chassis cools the heat exchanger, blows air across other components needing cooling, and removes heated air from the chassis. The air mover may extend substantially across the chassis, or it may blow crosswise from an outlet-ventilating direction.

A monolithic optical module of injection-molded high temperature polymeric resin combines an optical turn of typically 90 degrees together with dual or triple beam paths. No additional piece parts are necessary for achieving the optical turn, since this occurs by total internal reflection (TIR), and no additional piece parts are necessary for dual monitoring, which is realized by means of an air-gap functioning as a dual beam-splitter plate. The monolithic optical module further includes integrally surfaces for accurate alignment of the module with external optical elements, and can additionally include integral optical elements, for example lenses and thin film coatings.
