The present invention provides a wireless folding keyboard for a personal digital assistant which has a stand for supporting the personal digital assistant in the appropriate orientation to receive the wireless signals.
摘要:
Prior collapsible keyboards for personal digital assistants are overly complex and large. The present invention provides a folding keyboard for a personal digital assistant which folds up simply and in a small size and which is useful for standard typists. It is divided into two halves hingedly connected along a fold line. While the central or home row keys are standard size, the other two rows of keys are of reduced transverse dimension and are preferably so shaped as to allow a touch typist to use existing movements without missing the keys of reduced size, as are the keys at either end of all three rows.

A clamping device for securing a pair of clamps to the umbilical cord of a newly born infant includes pressure plates to remove blood from the section of the cord between the clamps. Thus, there is a greatly reduced risk of infection from blood squirting out upon the cutting of the cord during delivery of the infant.
摘要:
There is disclosed herein a device for clamping and cutting an umbilical cord so as to enable blood samples from the umbilical cord to be collected and/or tested. The device provides for the clamping of a severed end of an umbilical cord and the automatic ejection of that clamped end. The device also provides for the cutting of an umbilical cord without using excessive force regardless of the size of the umbilical cord. Additionally, the device provides for the valved use of vacuum tubes to collect umbilical cord blood samples. Furthermore, the device enables the measurement of blood values at the moment of cutting the umbilical cord. Finally, the device also provides for the protection of users and others from exposure to sharps and blood.
摘要:
A genetically engineered micro-organism having an operative metabolic pathway producing cinnamoyl-CoA and producing pinosylvin therefrom by the action of a stilbene synthase is used for pinosylvin production. Said cinnamic acid may be formed from L-phenylalanine by a L-phenylalanine ammonia lyase (PAL) which is one accepting phenylalanine as a substrate and producing cinammic acid therefrom, preferably such that if the PAL also accepts tyrosine as a substrate and forms coumaric acid therefrom, the ratio Km(phenylalanine)/Km(tyrosine) for said PAL is less than 1:1 and if said micro-organism produces a cinammate-4-hydroxylase enzyme (C4H), the ratio Kcat(PAL)/Kcat(C4H) is at least 2:1.
摘要:
A method for decoding a plurality of flash memory cells which are error correction-coded, the method may include: comparing physical values residing in the plurality of flash memory cells to a first set of decision thresholds thereby to provide a first item of comparison information for each of the plurality of cells; comparing physical values residing the plurality of flash memory cells to a second set of decision thresholds, thereby to provide a second item of comparison information for each of the plurality of cells, wherein neither of the first and second sets of decision thresholds is a subset of the other; and determining logical values for the plurality of flash memory cells by combining said first and second items of comparison information.
摘要:
A flash memory apparatus that may include a plurality of memory portions, and a controller operative to reserve for data retention purposes, for at least a first duration of time, only certain memory portions; allocate data, during said first duration of time, only to said certain memory portions, thereby to define a retired memory portion for said first duration of time; determine to copy data from a certain memory portion to a retired memory portion based upon a relationship between effective cycle counts of the certain memory portion and the retired memory portion, an effective cycle count of any memory portion is responsive to a number of erase-write cycles and to an effective duration of time the memory portion had available to recover from erase-write cycles; and copy the data from the certain memory portion to the retired memory portion.
摘要:
A method for decoding a plurality of flash memory cells which are error-correction-coded as a unit, the method comprising providing a hard-decoding success indication indicating whether or not hard-decoding is at least likely to be successful; and soft-decoding the plurality of flash memory cells at a first resolution only if the hard-decoding success indication indicates that the hard-decoding is not at least likely to be successful.
