Abstract: A downhole reaming system includes a tubular body having a drill bit disposed on a distal end thereof, and a central bore therethrough, wherein the tubular body is attached to a drillstring, an expandable reamer having cutter blocks coupled thereto and configured to selectively expand radially therefrom, a near-bit reamer disposed proximate the drill bit, the near-bit reamer having cutter blocks coupled thereto and configured to expand therefrom, and a measurement sub configured to measure at least one characteristic of an interior wall of an enlarged wellbore.

Abstract: A flexible member (114) for supporting a glove in a manner whereby it can be readily donned by a user without touching the exterior of the glove. The flexible member (114) having a substantially planar glove support portion (122) which, when viewed in plan, conforms to the shape of at least part of the interior of a glove and is fittable, in use, to the interior of a glove through the cuff aperture thereof, and an attachment portion (112) by which the flexible member (114) can be held to facilitate donning of a glove and the subsequent removal of the glove support portion (122) from the cuff aperture of a glove while the glove is worn by a user. The glove support portion (122) is of sufficient flexibility to deflect around the hand of a user as said hand is inserted into a glove supported by the glove support portion (122), and further to deflect around the wrist of a user as the glove support portion (122) is removed from the glove through the cuff aperture thereof.

Abstract: The present invention provides a support (200) for a glove (300). The support (200) is configured to releasably retain a glove (300) in a position which enables the glove (200) to be donned by a user and comprises a planar body (202) having at least one digit aperture (204, 206, 208, 210, 212) shaped to receive the fingers of a user, an inner glove retaining arrangement (230) provided around the at least one aperture (204, 206, 208, 210, 212) and an outer glove retaining arrangement (242) provided around both the first glove retaining arrangement (230) and the at least one aperture (204, 206, 208, 210, 212). The body (202) further includes at least one weakened region (220, 222) extending from the at least one digit aperture (204, 206, 208, 210,2 12), the weakened region (220, 222), in use, permitting the body (202) to tear and thereby increase the size of the at least one digit aperture (204, 206, 208, 210, 212) as the hand of a user is inserted into the at least one digit aperture (204, 206, 208, 210, 212).

Abstract: An improved binary search tree (BST) balancing facility balances BSTs by copying pointers to the nodes of a BST into a pointer list in accordance with a sequential order of respective data values of the nodes. The balancing facility then builds a balanced BST based on a first index to a first pointer of the pointer list and a second index to a last pointer of the pointer list. In an illustrative embodiment, the balanced BST is built by identifying a central pointer at a midpoint of the pointer list, a left range of pointers before the midpoint, and a right range of pointers after the midpoint. The central pointer is then interpreted as a pointer to a root node, and a balanced left subtree of the root node and a balanced right subtree of the root node are built based on the left range of pointers and the right range of pointers, respectively.

Abstract: A call is received at an operator station (200). If a position failure occurs at the operator station, the position failure is detected (204). A determination is made as to whether the call is an emergency call (206) by, for example, examining the sequence of called digits. If the call is designated as an emergency call, then a determination is made as to status of the call. Based on the status of the call, a connection is established with an alternate operator station without dropping the call to the caller.
