Abstract: Wavefront measurements of eyes are typically taken when the pupil is in a first configuration in an evaluation con-text. The results can be represented by a set of basis function coefficients. Prescriptive treatments are often applied in a treatment context, which is different from the evaluation context. Hence, the patient pupil can be in a different, second configuration, during treatment. Systems and methods are provided for determining a transformed set of basis function coefficients, based on a difference between the first and second configurations, which can be used to establish the vision treatment.

Abstract: Tarsands are an agglomeration of grains of sand coated with bitumen, called tar. In their natural state, tarsands are found in layers, or stratas. In the case of open pit mining, the layers of tarsands must be dug out using mechanical equipment. The mechanical equipment generate large clumps of tarsands.  These clumps have to be reduced in size, so as to make them suitable for transportation through pipes, using water as a transportation agent, for further processing.   The reduction into hydro-transportable size clumps is accomplished through the use of rotary crushers/  sizers. The main component of these crushers is one, or more, horizontal shaft fitted with teeth. The teeth have a crushing/sizing function, and also help the flow of the tarsands, by pushing the clumps of suitable size towards the hydro-transport system.   The crushing/sizing operation creates a very severe level of abrasion of the teeth. When the teeth are worn out, the equipment has to be stopped, and the teeth have to be changed.  This causes the production to stop, and the costs associated to this stoppage, combined with the cost of changing the teeth is very high.   The design of the teeth is a critical element in their resistance to abrasion.  The common concept is to design a steel tooth which can be hardsurfaced with some abrasion resistant material, so as to provide good mechanical properties and abrasion resistance. The tooth is then fixed onto a tooth holder secured to the shaft, and the crushing/sizing action is solely based on the mechanical characteristics of the tooth, which is then used as a sharp, spearing tool.   The TARTOOTH design enables the tooth to work as a pressure tool, instead of as a penetrating tool. It is based on the physical properties of the tarsands. The concave profile of the front part of the tooth enables the sand to pack in the cavity. The packed tarsands then act as base to apply the pressure created by the kinetic energy of the front of the tooth onto the big clumps of ore, and thus disintegrates them into smaller clumps. It enables to increase the life of the teeth, reducing the frequency of shut downs of the equipment and increasing effective production time. It also enables to address the seasonal changes in the summer and winter characteristics of the tarsands.

Abstract: A method for estimating the start time of an electronic pulse generated in response to a detected event, for example the start time for pulses received in response to photon detection in positron emission tomography, includes providing a detector that detects an external event and generates an electronic analog pulse signal. A parameterized ideal curve shape is selected to represent analog pulse signals generated by the detector. Upon receiving an analog pulse signal, it may be filtered, and then digitized, and normalized based on the area of the digital signal. Using at least one point of the normalized digital pulse signal, a curve from the parameterized ideal curve shape is selected, that best represents the received analog pulse signal, and the selected curve is used to estimate the pulse start time.
