Abstract: A digital signature scheme for a "smart" card utilizes a set of prestored signing elements and combines pairs of the elements to produce a new session pair. The combination of the elements is performed partly on the card and partly on the associated transaction device so that the exchange of information between card and device does not disclose the identity of the signing elements. The signing elements are selected in a deterministic but unpredictable manner so that each pair of elements is used once. Further signing pairs are generated by implementing the signing over an anomalous elliptic curve encryption scheme and applying a Frobenius Operator to the normal basis representation of one of the elements.

Abstract: A diaphragm pump is provided with a diaphragm
defining a pump chamber and a drive chamber in the pump
housing, a driving fluid is supplied to the drive chamber
and a pump fluid is expelled from the pump chamber. The
diaphragm pump is provided with pressure control means
which, when the pressure in the pump chamber surpasses the
pressure in the drive chamber neighboring the pump chamber
across the diaphragm, controls the pressure of the driving
fluid based upon output signals from pressure sensors in
such a manner that the pressure in the fluid chamber will
become higher than the pressure in the neighboring drive
chamber. This makes it possible to prevent a diaphragm
reversal phenomenon, wherein a diaphragm that should
expand toward the pump chamber contracts toward the
drive chamber instead during reciprocation of the
diaphragm.

Abstract: A multi-media messaging system (106) provides multi-media message access capability to non-subscriber message recipients (126) who lack multi-media message-reception capability. When a message originator (100) who is a subscriber requests a message to be sent to a recipient's address, the messaging system determines whether the recipient is able to receive at this address all of the media in which the message is expressed. If not, the messaging system saves the message for the recipient, assigns an identifier/password to the message, and creates a substitute message containing any components of the original message that are expressed in media which the recipient is able to receive at the address, along with the password and instructions on how to log into the sending messaging system. The messaging system then sends this substitute message to the recipient's address. When the recipient follows the instructions and logs into the sending messaging system with the password, the messaging system allows the recipient to access only the original message. Following this access, or if the access is not made within a predetermined time period, the messaging system deletes the original message.

Abstract: An optical wavelength converting device is provided with
a LiTaO 3  substrate, a plurality of inverted-polarization
layers periodically arranged in an upper surface of the LiTaO 3 
substrate, and an optical waveguide crossing the inverted-polarization
layers. The upper surface of the LiTaO 3  substrate
is directed toward a -X-crystal axis direction. The inverted-polarization
layers are formed by exchanging Ta +  ions of the
LiTaO 3  substrate for H +  ions. The substrate is formed by
cutting out LiTaO 3  crystal along a plane inclined to the C-crystal
axis towards the X-crystal axis. The spontaneous
polarization is directed in a +C-crystal axis direction.
The optical waveguide is formed by exchanging Ta +  ions of
the LiTaO 3  substrate and the inverted-polarization layers
for H +  ions to set a refractive index of the optical
waveguide higher than that of the LiTaO 3  substrate. The
optical waveguide extends in a -Y-crystal axis direction.
Fundamental waves polarized in a transverse electric mode
induce electric field directed in ±Y-crystal axis
directions and are converted into second harmonic waves in
the optical waveguide.
