One or more sliding latches, such as an upper right sliding latch 216, a middle right sliding latch 218, and a lower right sliding latch 220, may be used for locking the mated halves (front clamshell housing element 105 and rear clamshell housing 104) of clamshell housing 102. Other mechanisms may alternately be used to couple elements of the outer housing assembly in various embodiments.
Referring to FIG. 3, details of wheeled pipe inspection system embodiment 100, in a configuration where pull-handle 108 is stowed, are illustrated. As noted previously, pull-handle 108 may be seated into the handle stowage cup 126 and retained by the handle stowage clip 128.
The pull-handle 108 may include a handle mounting alignment mechanism for aligning pull-handle positioning and restraining pull-handle motion. The housing assembly may include a seating mechanism for securing the pull-handle during use, while readily allowing removal for stowage. For example, the handle mounting alignment mechanism may include as alignment pin 300 on pull-handle 108, which, when deployed, may drop into a seating mechanism, such as formed groove 302 on the handle accessory mount 109, for preventing rotation of the pull-handle 108. The formed groove 302 may be backed by a molded insert 303. In other embodiments, alternate alignment mechanisms, such as keyed slots, hinges, or other alignment mechanisms known or developed in the art may be used.
In an exemplary embodiment, a spring-loaded toggle 304 may move a lower pin (not shown in FIG. 3) into a lower hole 306 on the pull-handle 108 when it is fully inserted, to prevent the handle 108 from slipping upward when pulled, as well as preventing rotation. When the spring-loaded toggle 304 is pressed in, the lower pin (not shown) is withdrawn, allowing the pull-handle 108 to be removed from the groove 302 in the handle accessory mount 109.
One or more sliding latches, such as right upper sliding latch 216, right middle sliding latch 218, and/or right lower sliding latch 220 may be used for locking the halves of the clamshell housing 102 together. A push-cable, which may be spooled on a drum (not shown), which may be coupled to a pipe-inspection camera 308, may be fed from the inside of the outer clamshell housing 102 through an opening, such as a cable feed opening 310, which may be lined with a formed wear insert 312, or other friction-reduction mechanism, such as a bearing to aid in deploying and retracting the push cable.
A camera stowage mechanism, such as camera stowage clip 316, may be disposed on the outer housing, such as on a plastic front plate 314, which may be mounted on the front surface of front clamshell housing element 105. The pipe-inspection camera 308 may be stored under the camera stowage clip 316 when not in use and/or elsewhere on system 100.

FIGS. 28 and 29 illustrate flow charts describing two exemplary processes for enabling a computing device to view content from a smart cable storage drum, and to control certain aspects of a smart cable storage drum. One of skill in the art will appreciate various alternative processes for enabling such a computing device to view content from various resources in a system, including one or more inspection devices, other computing devices, and remote databases. Having access to content from various system resources enables a user of the computing device to enrich content received from an inspection device, correlate content from multiple resources, and better coordinate the efforts of one or more users in the system. Moreover, having access to content using one or more networks permits one or more users on the network(s) to view, manipulate, control the capture of, and manage the distribution of content from various locations and at various times.
For example, an electronic computing device, such as a personal computer, tablet device, smart phone, or other computing device, may access inspection data from a cable storage drum via a wired or wireless network (e.g., LAN, WLAN, cellular network, Internet, etc.), which may include a network hub disposed on or within the portable inspection device, such as within a hub of the cable storage drum or elsewhere in the cable storage drum. The computing device may also access related data from another system resource (e.g., another cable storage drum or inspection device, another computing device, or a backend database). Similarly, the cable storage drum may access the related data from the same resources. The computing device may then display the inspection data and/or the related data. A user at the computing device may also edit the displayed data and/or create data, and may distribute those edits and create data to the other resources in the system. The user may also control, over the network, any of the networked resources. Similarly, other users may also control any of the networked resources.
FIG. 30 illustrates details of an embodiment 3000 of a data transfer system between a battery and battery shoe disposed on or within the portable inspection system and a wireless transceiver disposed therein, such as in the hub or elsewhere in the inspection system. A battery 3050, which may be a standard rechargeable or single use battery or, in an exemplary embodiment, an intelligent or Lucid rechargeable battery such as described in U.S. patent application Ser. No. 13/532,721, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, filed Jun. 25, 2012, and U.S. Patent Application Ser. No. 61/663,617, entitled MODULAR BATTERY PACK APPARATUS, SYSTEMS, AND METHODS, INCLUDING VIRAL DATA AND/OR CODE TRANSFER, filed Jun. 25, 2012, may be coupled to a battery dock or shoe 3060 or other battery connection element. The battery may supply power to the portable inspection device through the shoe to power electronics, video cameras, such as camera 3010, wired or wireless transceivers, such as transceiver 3030, as well as other elements, such as a camera control unit (CCU) 3030, other wireless devices either in the portable inspection system or in other electronic computing devices, such as a second wireless transceiver 3020 as shown connected to the CCU 3030, and/or other components of the portable inspection system not shown in FIG. 30. In an exemplary embodiment, the wireless transceiver 3030 is a WiFi or other wireless LAN hub, node, or base station and is positioned in the cable storage drum, such as inside the cable storage drum hub, with the slip-ring connector 3067 used to provide electrical power and data signaling to the hub.
In operation, battery data may be provided from the battery 3050 through connection 3053 to the battery shoe 3060. The data may be passed directly through the shoe or may be modified by the shoe 3060 or other data format converter elements (not shown in FIG. 30) to reformat, change physical layer protocols, and the like, before being transferred through connection 3063 from the battery shoe 3060 to the wireless transceiver 3030 via an electrical connection (or optionally through other connections such as optical connections and/or wireless connections in alternate embodiments). Power may be supplied from the battery 3050 via power connection 3051 to shoe 3060, and then through electrical power connection 3061. Power may be further provided to camera 3010 and/or other devices through connection 3061 (not shown).
A slip-ring connector 3067 may be used in exemplary embodiments to provide power to the transceiver 3030 and/or camera 3010 through the hub while allowing the hub to rotate relative to the housing, however, in other embodiments alternate data connection mechanisms or direct wiring may be used between the battery shoe and transceiver. In an exemplary embodiment, a three wire connection 3065 as shown may be used to transfer both data and power between the battery shoe 3060 and transceiver 3030. However, other numbers of conductors may be used in various embodiment to provide either serial or parallel data as well as DC power (e.g., as positive and negative leads). Likewise, in an exemplary embodiment the slip-ring may be a three conductor slip-ring connector, but in alternate embodiments may include more than three connection paths depending on the provided power and data signaling (e.g., in embodiments with more than one voltage power supply, multi-conductor data signaling, etc.).
Image, audio, and/or video data and related information may be transferred from the camera 3010 to the wireless transceiver 3030. The video may be compressed in the camera in a video compression module (not shown) to compressed formats such as MPEG4, H.264, and the like to reduce required transmission bandwidth. Video, audio, images, battery data, and/or other data or information may be transmitted wirelessly via connection 3021 from transceiver 3030 to another wireless node, such as to optional wireless transceiver module 3020 or to other wireless nodes, such as nodes on other external electronic computing devices 3080 such as portable or notebook computers, tablets, smart phones, and the like.
