摘要:
The present invention is directed to a method of manufacturing spectacle lens eyewear using a block mold, front and back optical inserts, front and back optical insert gaskets, a protractor insert, a closing mechanism and a preformed frame, the method comprising the steps of: selecting a front optical insert from a look up table or computer program product and assembling the insert into the block mold; selecting a front optical insert gasket and assembling the gasket onto the front optical insert; assembling the frame front onto the front optical insert gasket; selecting a back optical insert gasket and assembling the gasket onto the back side of the frame front; selecting a back optical insert from a look up table or computer program product and assembling the insert onto the back optical insert gasket; assembling the protractor insert and adjusting the position of the back optical insert to the axis indicated on a look up table or computer program product; assembling the mold closing mechanism and securing the mold; filling the cavity through a first capillary tube; curing the closed mold to polymerize the lenses; removing the ophthalmic eyewear from the block mold and releasing the front and back optical inserts and insert gaskets; and removing the capillary tube housing and attaching earpieces.
摘要:
A programmable serializer comprising a multi-bit input port, a multi-bit output port, at least one multiplexer and at least one programmable address counter corresponding to the multiplexer for generating a sequence of multiplexer data input addresses that are inputted into the multiplexer address input. The multiplexer has an output connected to the multi-bit output port, an address input and a plurality of data input channels having addresses. Each data input channel is connected to a corresponding bit of the multi-bit input port. At least one data input channel is coupled to the multiplexer output when the corresponding address of the data input channel is applied to the address input. The programmable address counter receives and stores an initial address value, an address increment value and a count value and generates a sequence of addresses based on these values. The initial address value represents the multiplexer data channel that is to be initially coupled to the multiplexer output. The address increment value represents the increment that must be added to a current address in order to reach a next address. The count value represents the number of address that must be generated by the counter prior to restarting the sequence at the initial address value.
