title: A high-resolution full-field range imaging system

authors: Carnegie, Dale A.

subjects: image resolution

abstract: There exist a number of applications where the range to all objects in a field of view needs to be obtained. Specific examples include obstacle avoidance for autonomous mobile robots, process automation in assembly factories, surface profiling for shape analysis, and surveying. Ranging systems can be typically characterized as being either laser scanning systems where a laser point is sequentially scanned over a scene or a full-field acquisition where the range to every point in the image is simultaneously obtained. The former offers advantages in terms of range resolution, while the latter tend to be faster and involve no moving parts. We present a system for determining the range to any object within a camera's field of view, at the speed of a full-field system and the range resolution of some point laser scans. Initial results obtained have a centimeter range resolution for a 10 second acquisition time. Modifications to the existing system are discussed that should provide faster results with submillimeter resolution.

title: Using the criminal law computer misuse provisions to protect confidential information

authors: Kingsbury, Anna

abstract: This article is about the criminal law provisions relating to crimes involving computers, and the risks these provisions may pose to people dealing with confidential information in the nature of a trade secret, as illustrated by recent cases.
There is a growing international trend toward use of the criminal law to protect confidential information and trade secrets. A growing number of jurisdictions have criminal provisions applying in some form to the taking of trade secrets. United States law has included such criminal provisions for some years. New Zealand law has also had provisions since 2003, and requirements for such provisions are being included in trade agreements such as the Trans-Pacific Partner-ship Agreement (TPPA). The primary justification for criminalisation is generally concern about foreign hackers, but inevitably employees and ex-employees are among the likely defendants.
There has not yet been a lot of case law involving the taking of confidential information under the New Zealand provisions, but there have been two significant recent cases. This article reviews the recent New Zealand cases and considers the implications for employees and others dealing with confidential information. It is arguable that the availability of the criminal law in these cases creates excessive risks for individual employees and more broadly for employee mobility and the sharing of information, perhaps most troublingly in knowledge-based industries.

title: A game of slides and ladders: Māori health providers and funders

authors: Masters-Awatere, Bridgette

abstract: Devolution of government responsibility after the neo-liberal reforms of the 1980s, and the re-orientation of health services towards public health in the 1990s, created an opportunity for Māori to take control of their own health outcomes through the delivery of culturally relevant and appropriate services. By 2000 “By Maori, For Maori” service provision had burst forth as the preferred approach with Māori. While grappling with the tendency of government agencies to fund services based on pre-existing health output criteria, Māori service providers were “walking on egg shells” under the constant threat of losing their funding. Currentcontracting does not capture the extent of the work done by Māori providers to serve precariat families. Nor does it adequately acknowledge, validate or value indigenous approaches to health and wellbeing. Instead, narrow, administratively demanding and difficult to interpret contracts threaten the provision of culturally relevant services. This chapter talks about some of the creative and insightful ways Māori service providers manage contrasting cultural and contractual expectations.
